Muscular System Essays (Examples)

Muscular System and Exercise the

Disuse atrophy of the muscles is caused by prolonged inactivity, which often occurs after sustaining an injury. Hypertrophy of the muscles is achieved through regular diet and exercise. 1(p127) Two types of training, strength and endurance, greatly increase muscle condition. Strength training increases muscle condition through the use of resistance. While conditioning through resistance will increase the number of myofilaments in muscle fiber and increases muscle size, it will not increase the number of muscle fibers.1(p128) Resistance training has been shown to positively affect heart rate, stroke volume, and cardiac output, though not to the same extent as has been found through the extended practice and implementation of endurance training. 2 Long-term resistance training has also been found to reduce the resting heart rate, increase stroke volume at rest and exercise, maintain cardiac output at rest, decrease resting systolic and diastolic blood pressure while at rest, improve resting lipid levels,…… [Read More]

Muscular System Function of Action Potentials The

Muscular System

Function of action potentials?

The function of action potentials is to rapidly communicate information within a neuron, coupling the neurons "input," either synaptic, sensory or intrinsic stimulation with its output, neurotransmitter secretion.

Cell electrical properties are the result of?

Cells use atoms that have become charged as a result of gaining, or losing, valency shell electrons. Cells are wet circuits that operate in a salty, conductive, medium.

How is the outside surface of the plasma membrane different from the inside surface?

The outer and inner surface of the plasma membrane of quite different. They form two separate water interacting surfaces, and proteins coat the outer surface. Although proteins extend through the membrane, they are only exposed on the outer surface. By means of selective permeability, the outer surface has a higher positive charge than its inner surface

Muscular System the Normal Anatomy and Physiology

Muscular System

The normal anatomy and physiology of a muscle determines its capability of formulating a contraction. The contraction of a muscle is dependent on the ability of a neuron to become excited through a process that includes a concentrated flow of sodium (Na+), potassium (K+), and calcium (Ca+) through the neuron and eventually into the muscle cell (Tortora & Derrickson, 2011). A neuron begins its resting membrane potential at -70mv. In order for an action potential to occur, which is the event that will precede the muscle contraction, the membrane must first depolarize and become more positive, reaching -55mv. Once -55mv is reached, the membrane is said to be at the threshold potential, the voltage by which most Na+ channels in the cell membrane would open. After the first Na+ channel opens, the cell becomes even more depolarized and Na+ ions move into the cell (Martini, Nath, & Bartholomew,…… [Read More]

Skeletal and Muscular Systems

Skeletal and Muscular Systems:

The human body is made of several parts and systems that perform various functions to sustain an individual's life. The skeletal and muscular systems are examples of important systems in the body with various functions. The skeletal system can be described as the body framework on which the human body is built (Turley, 2011). This system is made of 206 bones in addition to ligaments and cartilage in order to provide structural support for the body. This system is also known as the skeletomuscular or musculoskeletal system since it works with the muscular system to sustain body posture, generate movement, and protect the major organs of the body. The various bones that form the skeletal system are divided into various categories including axial skeleton and appendicular skeleton.

In contrast, the muscular system provides movements to the bony framework of the body and is made of nearly…… [Read More]

Tissue Maturation Body System Effects

e. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying upon the reserve capacity of the heart to provide the endurance needed to perform such activities. If an elderly person does not engage in some sort of endurance-based activities, he or she will not have the cardiac reserve capacity needed for daily tasks. More importantly, diminished capacity may not counteract illnesses or diseases. Although strength-based activities help the cardiac reserve, it may not benefit the skeletal system. "While resistance exercise promotes fiber hypertrophy in skeletal muscles, the explosive power of…… [Read More]

Main Systems of Human Body

The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood.

The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within the heart's lower half, are responsible for pumping blood to the whole body (away from our heart), whilst the atria, situated within the heart's upper half are in charge of receiving blood from different parts of the human body. The right and left ventricles pump de-oxygenated and oxygenated blood, respectively; de-oxygenated blood is pumped to lungs while oxygenated blood is pumped to the remainder of the human body (smith, 2013). These 4 chambers are connected to one another by…… [Read More]

Skeletal System Purpose and Functions

Calcium is needed in blood clotting, stability and permeability of the membrane, nerve conduction, muscle contraction, cellular secretion, enzyme activity, and cell growth. Magnesium is needed for the metabolism of potassium and calcium and for the mobilization of calcium from bones. Phosphorus plays and important role in the development and maturation of the bone. Its chief role in bone resorption, mineralization and collagen synthesis makes it essential in calcium homeostasis (Michael's).

Diseases and disorders of the skeletal system include leukemia, bursitis, osteoporosis, sprains, fractures, spina bifida, scurvy, arthritis, scoliosis, talipes equinovarus or clubfoot, tendonitis, kyphosis and poliomyelitis (Family Shock 2001). Leukemia is also called cancer of the blood where abnormally large numbers of white blood cells multiply at an uncontrolled manner so that they interfere with the body's production of red blood cells. The cause is still unknown. ursitis is a painful condition, which most commonly affects the hips and…… [Read More]

Cardiovascular and Gastrointestinal Systems Integrated

Integration of Cardiovascular/Gastrointestinal Systems

Integration of gastrointestinal and cardiovascular systems within the human body

The integration of the gastrointestinal and cardiovascular systems allow for nutrients to be introduced, broken down, and absorbed by body to maintain and promote healthy bodily functions. Independently, these systems serve separate functions, but when working in conjunction, help to transport necessary nutrients throughout the body, while maintaining and promoting homeostasis within the systems. Any imbalance within these systems will greatly affect the body, as a whole, and can lead to potentially fatal results.

Integration of gastrointestinal and cardiovascular systems within the human body

The gastrointestinal and cardiovascular systems of the human body help to breakdown and transport items that are ingested, such as food and medication, to the necessary parts of the body, expelling wastes that are not needed. Separately, the gastrointestinal and cardiac systems have different functions, but when the systems work in conjunction…… [Read More]

Adrenal Gland Keeping the Body

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…… [Read More]

Anterior Cruciate Ligament or ACL

esearchers believe that incorporating evidence-based prevention methods can decrease the incidence of ACL ruptures, but an understanding of the etiology and mechanisms of sports injury are a necessary to do this (Posthumus, 2009).

The highest prevalence of extrinsic ACL injuries tends to occur in organized sports especially adolescents participating in pivoting type sports such as football, basketball, and team handball (Bahr & Krosshaug, 2005). In addition to any intrinsic factors and adolescent may have, or predisposing factors, environmental factors surrounding organized sports can also play a role in injury. For example, weather conditions (slippery surface), type of surface sport is played on (grass vs. pavement), proper footwear, and protective bracing (Posthumus, 2009).

A growing concern regarding these injuries and the populations that incur them is that these injuries increase the risk of osteoarthritis (Bahr & Krosshaug, 2005). In fact, after ten years, around half of all people that have suffered…… [Read More]

What Happens When I Get Burned

Burned

There are specialized cells called receptors that receive information about the environment and changes in that environment. Each kind of receptor reacts to a different kind of stimulus. For example, the receptors on the retina in the eye detect light. Receptors are all connected to nerve cells, and the nerve cells carry information from the receptor to the brain, where the signal is processed. The brain makes the decision about what to do with the information, such as move a part of the body to cause a reaction based on the information the receptors sent. However, in the case of an emergency situation, this normal interpretation process takes too long even though it is extremely fast, and instead another emergency plan is followed by the nervous system. When burned the body will experience a reflex reaction.

The skin has receptors that detect both pressure and temperature. In the case…… [Read More]

Edwards syndrome which is also known as Trisomy 18 is a genetic disorder that is caused by the presence of a third copy of chromosome 18 instead of the normal two copies. The extra 18th chromosome comes as a result of nondisjunction of the chromosomal material during meiosis. As a result of failure in the segregation of a chromosome to the daughter cells, there can be errors in the meiotic division leading to an extra chromosome. This extra chromosome usually occurs before conception and it is the second most common autosomal trisomy that carries to term after Down syndrome though it is more common in females than males…… [Read More]

Electromyography Biopac Exercise Discussion This

The authors were trying to develop a system of estimating and indexing muscle fatigue rates during static muscle contraction. The results of this study indicated that estimations were reasonably successful with some limitations that were noted. One limitation was that the study neglected muscle recovery since the experiment was performed in a lab under controlled conditions and the muscles were able to fully recover. However, in the real world muscles move in a dynamic environment thus making muscle recovery rates a challenge in producing an accurate estimate of fatigue.

Another study looked at the efficacy of treatments in patients who suffer from Carpal Tunnel Syndrome (CTS). The study conducted research using 111 patients who suffer from CTS. They compared the standard conservative treatment (SCT) with other forms of treatment available that also propose to alleviate symptoms associated CTS. They found that SCT, which includes local steroid injections, was effective as…… [Read More]

Biology Function of the Metabolic

d.).

The primary organ that is accountable for regulating metabolism is the hypothalamus. The hypothalamus is situated on the brain stem and forms the floor and part of the lateral walls of the third ventricle of the cerebrum. The main functions of the hypothalamus is to control and integrate activities of the autonomic nervous system (ANS), production and regulation of feelings of rage and aggression, regulation of body temperature and regulation of food intake (Graham, 2005).

BM goes down with age and with the loss of lean body mass. Increased muscle mass and cardiovascular exercise can help to increase BM, even when the body is at rest. Measured in calories, metabolic rates vary with exertion, recent food ingestion, muscle exertion, environmental temperature, emotional state, body temperature, pregnancy, menstruation, level of thyroid hormones stress hormones (epinephrine and norepinephrine), fear and illness. The human body requires energy in order to stay alive…… [Read More]

Market Driven Management

Pharmaceutical industries have to operate in an environment that is highly competitive and subject to a wide variety of internal and external constraints. In recent times, there has been an increasing trend to reduce the cost of operation while competing with other companies that manufacture products that treat similar afflictions and ailments. The complexities in drug research and development and regulations have created an industry that is subject to intense pressure to perform. The amount of capital investment investments required to get a drug from conception, through clinical trials and into the market is enormous. The already high-strung pharmaceutical industry is increasingly investing greater amounts of resources in search of the next "blockbuster" drug that can help them gain market position and profits. Laws, regulations and patents are important to the industry while spending billions of dollars in ensuring the copyright of their products.

It is the intention of this…… [Read More]

Fibromyalgia

Having many physical and clinical symptoms, Fibromyalgia is a syndrome whose effects are felt in form of extreme musculoskeletal pain. It is believed that many environmental, genetic and biological factors are responsible for the start and progress of this infection although its etiology is undermined. In many industrialized countries, its rate of occurrence is 0.7-4.7% amongst the general population. It is incidentally seen more in women than men and the general female-to-male ratio being 9-1. Due to the diverse nature of its symptoms, those infected experience major difficulties adapting to their working environment, family or their life. It also subjects the sufferers to use consultative health services and social resources…… [Read More]

Lungs What Are the Lungs

However, it was 1953 that the formation of serotonin was from the lungs was substantiated. It is also observed that detoxification of the blood takes place in the lungs. Later, it was observed that one of the important activities of the lung is to provide chemical filtration by shielding the regular circulation of blood from the attack of vasoactive mixtures and other exogenous compounds present in the arteries. The physiology of the lungs and its location makes the lung exclusively suitable to perform these activities. (Wet; Moss, 1998)

The total output from the cardiac system is obtained by the lungs whereas other organs acquire only a very small quantity of output. The blood that circulates the lungs is subject to the vast capillary endothelial plane of the body which is of seventy square meters. This aspect of output and circulation enable the lung to perform the efficient function of biochemical…… [Read More]

The success was remarkable, according to the researchers: Even muscles that had already lost half of its mass, recovered visible. (Leppanen et al. p5549-65) At the same time, the mice survived for several weeks longer than their untreated counterparts and also developed a healthy appetite again. (Mantovani, p296) The new study is therefore interesting in two respects: First, it demonstrates that the muscle loss at least in animal models in fact, affects the chances of survival, and secondly, it shows a way, may be how to prevent this degradation, and even reversed. (Bruera et al. p857)

The heart is an essential organ in the human body, it keeps the individual alive. Understanding how the heart operates and functions is essential to help protect your heart from heart disease. Cardiac arrest and coronary heart disease are significant heart related illness that has a high mortality rate. It is important for individuals with pre-existing heart disease to understand the symptoms of cardiac arrest and coronary heart disease, since these are both leading causes of fatality in the United States. Understanding how the heart works, the individuals risk for heart disease, and how to prevent or delay heart disease is essential. In this paper I will address the relationship between cardiac arrest and coronary heart disease. I will also explain how the heart functions and discuss some ways of preventing cardiac arrest and coronary heart disease.

Phylum Annelida

Phylum Annelida

Annelids are members of the Superphylum Lophotrochozoa. The division of the Phylum is in three classes Hirudineans (leeches), Oligochaetes (earthworms) and Hirudinean (Polychaetes and leeches). They inhibit marine aquatic with Parapodia, like nereis Meglitsch P, 1972()

They are worm like animals that have muscular body walls that elongate. They are also circular in cross section. The major difference between Phylum Annelida and other worm like creatures is that, they have segmented bodies (also known as metameric). Each segment has its own particular function. Phylum Annelida include different types of earthworms, leeches and marine polychaetes. There are those that live in fresh water, marine also terrestrial. Some of them live as parasites.

Michelangelo and the Sistine Chapel

Michelangelo’s Creation of Adam

The Creation of Adam (1512) as conceived and depicted by Michelangelo represents a significant moment in art history because it brings a humanistic style of expression and sense of realism to the art world that had not existed prior. The work is focused almost exclusively on the Body as a subject. The two figures—God the Father and Adam—represent the majesty of the human anatomy in its ideal form: muscular, flexible, unique, authentic, poised, admirable, beautiful and proportional. In the painting, God is mostly draped with a thin cloth; Adam is completely nude and his position (reclined with one knee propped up while he stretches backwards and reaches forward languidly) suggests one of royalty being wakened after a long slumber. Indeed, the idea that Adam is like royalty is one that Michelangelo infuses into the scene giving the painting its high-minded rapturous quality, which is much in…… [Read More]

Perioperative Nurse's Role in Caring for Pregnant Patients With Aortic Dissections

Aortic dissection is a disease of the wall of the aorta in which the aortic blood bursts into the muscular layer of the great artery, thus forming a blood filled channel along the planes of the muscularis layer. This false lumen can re-rupture back into the true lumen, through a second distal intimal tear, creating a biluminal or double barrelled aorta. Due to weakened walls, there is threat of rupture into the surrounding tissue with fatal consequences. (Boon, , Colledge, Walker, & Hunter, 2010)

The pathophysiology behind the condition is often a spontaneous or iatrogenic tear in the intima. However, in about five to ten percent of patients, these tears are absent. An intimal tear can occur anywhere along the aorta, although a vast majority of tears are found within ten centimeters of the aortic valve. The dissection may extend towards the heart, affecting the coronary arteries, or it may…… [Read More]

Journey Begins as We Enter

The blood in which we are traveling in is composed of red blood cells called hemoglobin, plasma, platelets, and white blood cells. Blood is transported through the body by the heart's pumping action. As we continue, we will enter the hepatic portal vein, which delivers blood from the gastrointestinal tract to the liver, into the ascending aorta, up towards the heart. As we approach the heart, it's pumping will pull us up into its chambers and through to the lungs where we will get oxygen and continue our journey to the kidneys. As we return to the heart, we will pass through the aortic arch and descend through the thoracic aorta continuing past the descending abdominal aorta until we reach the renal artery. We will make a left turn and pass through the glomeruli through the kidney's tubules and conclude this phase of our journey into the left kidney.

Living Things Are Characterized by the Following

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

Houdini Was Able to Modulate His Normal Physiology During His Stunts

The objective of this study is to examine how Houdini was able to modulate his normal physiology during his stunts.

Harry Houdini caused the world to marvel at his skill in escaping the bondage of handcuffs and was referred to as the 'handcuff king' and as well Houdini performed many other magic tricks that required more than merely illusion but instead required that he be able to alter his own body's physiology. The modulation of physiology enabled Houdini to accomplish great feats and to capture the imagination and attention of a large base of fans across many years. Houdini is well-known for having spent a great deal of time and effort to invalidate individuals who were so-called mediums communicating with the dead because he detested this type of trickery.

Transfer of Maxillomandibular Relationship From

The understanding of TMJ anatomy as well as its function is very important to generate stable as well as healthy intercuspation. TMJ consists of condyle, disk, muscles and ligaments. It connects the lower jaw to the temporal bone in the skull in both sides and has two movements (osenstiel and Land, 2001). The TMJ along with muscles stabilization is the starting point to get the ideal maxilla-mandibular relationship in the centric relation. There is no way to register and transfer an accurate interocclusal record if patient has TMJ or muscles dysfunction. The patient with this dysfunction should be treated first before final restoration, cementation or construction. The conservative management of unstable joints and muscles via appliance therapy is the most common modality of management (Capp and Clayton, 1985).

Alzheimer's Disease According to the

One of the most common mental disorders linked to Alzheimer's is depression which according to Elwood Cohen manifests itself in three important ways. First, "There are higher rates of depression among Alzheimer's patients than among non-demented adults;" second, "Having a depressive episode is associated with an increased risk for developing Alzheimer's," and third, Depressive symptoms can be confused with dementia in older adults" (1999, 214).

In a recent study conducted by the Cardiovascular Health Initiative, based in Washington, D.C., more than one-third of 400 dementia patients and more than one-fifth of 300 patients with mild cognitive impairment (MCI) had experienced symptoms of depression during a one-month period prior to the study. Similar results were reported by the Multi-Institutional esearch in Alzheimer's Genetic Epidemiology (MIAGE) which discovered that "In the year prior to a patient being diagnosed with Alzheimer's disease, the same patient was almost five times more likely than their…… [Read More]

Stoppage of varying types of disorders is possible through learning in consideration of human development the number of genes contained in a single genome, their respective location and the establishment of functions or roles in the various genetic processes. This is achievable through strategized genetic mapping, where the establishment of specified genes having same linkage involved. The mapping establishes the respective linkages between genes and as a result of their location in the same gene, the crossing over frequency with the existing distance amid them is notable (Cummings, 2010, pg 333). esearch on the various risks factors involved can also be considerable as beneficial.

Neurotransmitters Are Chemicals Endogenously Produced in the

Neurotransmitters are chemicals endogenously produced in the body for the purpose of sending stimulus across from one neuron to the other through the synapse. Neurotransmitters, packaged in synaptic vessels, are clustered beneath the inner membrane of the axon terminal of the presynaptic membrane. The neurotransmitters upon stimulus are released into the synaptic cleft where they diffuse and attach to their particular receptors on the post synaptic membrane. The flow of action potential is the main stimulus to the release of the neurotransmitters. The main function of the neurotransmitters is to excite or inhibit certain kinds of receptors. Thereby the behavioral effect of the neurotransmitters depends on the kinds of receptors on the post synapse. Noradrenaline, an important neurotransmitter is involved in arousal and dopamine controls motor movements and cognition (Webster, 2001, p. 55).

Senior Fitness

* The effects on normal aging and metabolism is that after the age of forty, metabolism usually decreases by about 5% every ten years. That does not mean that metabolism cannot be controlled to some extent; it can. Metabolism is loosely defined as the chemical workings within our bodies that help us to maintain a certain level of energy use, calorie burning and general energy (even at rest). As we age, our metabolism rate slows down, meaning that we burn less calories and the ones we do burn are burned at a slower rate. It also means that we may have less energy and our overall health slows as well.
* As individuals grow older their muscle mass is less likely to maintain its composition. Bill Sonnemaker, the 2007 IDEA Health and Fitness Personal Trainer of the year states that building muscle mass at any age provides a number of…… [Read More]

Digestive System Disorder Case Study: Gastroparesis

The paper opens with an introduction and definintion of Gastroparesis and its association to damaging of vagus nerves along the intestines and stomach muscles. This reduces their ability for function properly. People living with diabetes have a higher likelihood of advancing Gastroparesis against sequential Diabetic Gastroparesis. More persons are contracting Gastroparesis during surgical operations. The paper illustrates that more patients are yet to find a cause linking their illnesses with Gastroparesis because it triggers Idiopathic Gastroparesis. The scope of Gastroparesis has a close link to diseases of connective tissue such as Ehlers-Danlos syndrome as well as scleroderma. The neurological conditions worsen along Parkinson's disease. The paper concludes with proposals of Gastroparesis diagnosis through tests carried out on gastric emptying scans, x-rays, and manometry. Clinical Gastroparesis takes the definition of stomach emptying complications. There are beneficial adjustments to insulin dosage among diabetic people who…… [Read More]

Dangers Outweigh Benefits of Genetic

Researchers at Cornell University discovered that Monarch butterfly caterpillars died when they ate plants dusted with the pollen of Bt corn that was growing in nearby fields, and many scientists worry that with so much insecticide in the corn plants, insects might develop a resistance to it (Dyer 2002). These fears and concerns are echoed by Francis Fukuyama who believes that genetic enhancement will undermine the system of human rights by disrupting the boundary that encloses all humans in a single group, thus believes society should limit genetic science to allow therapy but prohibit enhancement, such as genetically altered food crops, and non-therapeutic procedures (Tobey 2003). In other words, enhancement will allow society to increase genotypic and phenotypic diversity, yet such diversity will press society to the point of losing its shared humanity (Tobey 2003).

Effects of Massage on Depression in Newly Widowed Elderly Females

Therapeutic Massage on Elderly, Grieving Widows

The prosperity of a country is in accordance with its treatment of the aged," states an ancient Jewish Proverb ("Massage for the Mature Adult," 2001). This is an honorable and true statement. Too often many of our elderly people's needs are not noticed or attended to by family, friends, or medical practitioners. This is especially true for older women whose husbands have died.

Widowhood can have a tremendous impact on the health of older women (Ferraro, 1989; owling, 1987; Gass & Chang, 1989). The death of a spouse or partner has been described as the most disruptive and difficult role transition that an individual confronts throughout the life course (Lopata, 1987). In the United States, over 49% or 8.4 million women over the age of 65 are widows (radsher, 2000).

What Is the Best Exercise

Tai Chi is a series of postures and exercises developed in China as a system of self-defense and as an aid to meditation. It focuses on graceful movements that resemble a slow-moving dance routine combined with deep breathing throughout the routine. The result is a moving meditation that nourishes and balances both the body and mind.

Research studies of the benefits of tai chi show a significant decrease in the incidence of stroke and stroke mortality, as well as an increase in bone density. Studies also show a decrease in blood pressure in hypertension patients and an increased sense of well-being.

Because of the low heart rate routines, tai chi offers a safe alternative to aerobic type exercises for those prone to cardiovascular disease.

Tai Chi strengthens the joint musculature and increases the range of motion and flexibilty. Although a weight-bearing exercise it allows stimulation of bone growth without the…… [Read More]

The David Zwirner Galley and the Guggenheim

Art is something that can be appreciated in several ways. Thanks to the various museums cities have to offer, one can visit numerous places and see exhibitions from various artists. Two such places are the David Zwirner Galley and The Guggenheim. Both places have introduced audiences to interesting and thought-provoking works of art. Four of which will be featured here. The artists of the four works are Robert Crumb and Paul Cezanne.

David Zwirner Gallery is a modern art gallery located in New York City, offering another location in London. Owned by David Zwirner it features of collections of artists like Robert Crumb. For twelve years from 2000-2012, the Gallery was known as Zwirner & irth Gallery.

The R. Crumb Art & Beauty exhibition which opened April 15th and ends June 2nd, 2016, is an exhibition featuring various sketches. Lined up in a stark, white room, these black and white…… [Read More]

Shin Splints From Ecs Conditions

Practical esearch Finding Implementation and Experimentation Stage -- Phase I

The experimenter did not set out to determine specifically which of the various contributing factors (or combinations of factors) identified by the empirical research of medial tibial stress syndrome was most responsible for the experimenter's symptoms. However, since the initial attempts to resolve the symptoms incorporated changes to all of the external variables except a change in running surface, the experimenter immediately sought a softer running surface and temporarily abandoned running on any hard surface that magnified instead of minimized the physiological trauma associated with running on harder surfaces.

Because the empirical research also implicated poor running stride mechanics and excessive vertical elevation, the experimenter devoted considerable attention to making the following specific changes to the running stride: (1) shorter strides to minimize travel of the body while neither foot is in contact with the running surface; (2) conscious attempts…… [Read More]

Ergonomics Repetitive Movement Ergonomics Injuries

Repetitive Motion Injuries can be prevented through a proper workplace setup. Once a worker makes these adjustments to the work area, it is possible to feel more natural about working and be more productive. In addition to exercise, a person should do the following:

• Take short, frequent breaks from computer work. Suggested 10-15 minutes break away from the computer for every hour on the computer.

• Get up and move around whenever feeling symptoms

• Give input when the department is purchasing furniture and computer equipment

Here are other suggestions for repetitive syndrome in a work setting:

If it is not possible for someone to get down to the work load, he/she should bring the work load up. Then, when standing, he/she should not over reach and maintain an upright posture. The longer the handle, the more force it takes to use and lift that tool. Position oneself so…… [Read More]

Gastrointestinal Stromal Tumors

Epidemiology

Liegl-tzwanger, Fletcher and Fletcher (2010) pointed out that the exact incidences of gastrointestinal stromal tumors in the United States and Europe is not easy to determine. This is attributed to the fact that GISTs got proper recognition as well as diagnosis from the late 1990s.Studies carried out in Iceland ( Tryggvason et al.,2005), Sweden (Nilsson et al.,2005), as well as Holland (Goettsch,2004) have indicated that close to 11,14.5 and 12.7 cases per million people per year respectively.Incidences if GISTs have been shown to be higher as a result of the fact that most patients live with it for several years and it gets detected only during gastrectomy or autopsy all of which are usually performed for other reasond. study by gaimy et al.,(2007) which was performed consecutively on autopsies indicated that small GISTs having between 1-10 mm in about 22.5% of the individuals aged above 50 years.These small GISTs…… [Read More]

Charcot-Marie Tooth Syndrome Definition and

In the third trimester of pregnancy, caution must be taken concerning congestive heart failure, hypertension and decreased renal and hepatic function, interstitial nephritis, hyperkalemia, hyponatremia and renal papillary necrosis, anticoagulation abnormalities, leucopenia, granulocytopenia and thrombocytopenia. The use of Celecoxib is aimed primarily at suppressing pain and inflammatory stimuli, but it may contribute to NSAID gastrointestinal toxicity. The lowest possible dose of celecoxib should be prescribed and taken. On the whole, NSAIDs can mask the usual signs of infection, therefore, caution must be taken in the presence of existing controlled infection. The physician should investigate symptoms and signs, which suggest liver dysfunction or abnormal liver lab results.

On September 30, 2004, Merck and Company voluntarily withdrew rofecoxib from the American and world markets because of its association with an increase in cardiovascular incidence (Keldaya 2005). A major Food and Drug Administration study linked the medication to a three-fold rise in the…… [Read More]

Flexibility Training

flexibility training has to offer in everyday life of people by helping them to function more effectively. Moreover I shall discuss constructing a class specifically for this kind of training and also shed some light on the ways music can help motivate and improve the performance of the people undergoing the flexibility training.

BENEFITS OF FLEXIBILITY TAINING:

Flexibility comprises full range motion of the various joints of the body and encompasses all components of the musculoskeletal system and specific neuromuscular pathways of the body. Flexibility varies from person to person depending on his age, gender, body temperature and the type of joint to be moved. It helps in the reduction of low back pain and injury (Bach, Green, & Jensen) and also helps improve the posture and muscle symmetry. (Corbin, C.B., & Noble, L). In addition to all this it decreases severity due to injury, delays the onset of muscular…… [Read More]

Acclimatization Ascending to Higher Altitudes

(1989). These researchers investigated skeletal muscle adaptations in response to acclimatization at high altitude. Samples of muscle extracted before reaching high altitude and after returning to sea-level showed that maximal activities of enzymes, such as those representative of beta-oxidation, were unchanged. However, after exposure to extremely high altitude hypoxic conditions, reductions were observed in succinic dehydrogenase, citrate synthetase and hexokinase. The findings of this study did not support the researchers' hypothesis that extremely hypoxic conditions elicit changes that are adaptive toward maximizing oxidative function at the intracellular level (Green et al., 1989).

Diathermy Uses Benefits and Risks as One

Diathermy: Uses, Benefits, And isks

As one of the oldest treatment modalites, the therapeutic effects of heat have been experienced for several hundred years. In order to use heat in the treatment of deep muscle injury, diathermy treatment is the therapy of choice. Diathermy uses high-frequency electrical currents to heat deep muscular tissues. This heating results in pain relief, increased blood flow, and increased flexibility. esearch has demonstrated evidence both for and against the effectiveness of diathermy treatment. Attention must be given, however, to risk factors predisposing some patients to serious adverse effects due to diathermy treatment.

Diathermy: Uses, benefits, and risks

Diathermy refers to the use of high-frequency electrical currents to heat deep muscular tissues. This heat increases the flow of blood to the area, which in turn, speeds up recovery. The term diathermy is a derivative of the Greek words therma, meaning heat, and dia, meaning through. Therefore,…… [Read More]

Ergonomics Also Known as Human

Use tools and equipment that are properly designed to reduce the risk of wrist injury, (Zieve & Eltz 2010)

Workstations, tools and tool handles, and tasks can be redesigned to enable the worker's wrist to maintain a natural position during work, (National Institute of Neurological Disorders and Stroke 2010).

Ergonomic aids, such as split keyboards, keyboard trays, typing pads, and wrist braces, may be used to improve wrist posture during typing, (Zieve & Eltz 2010)

Training and awareness; the encouragement of frequent breaks; yoga classes offered for free at the workplace; job rotation.

Employers can develop programs in ergonomics, the process of adapting workplace conditions and job demands to the capabilities of workers, (National Institute of Neurological Disorders and Stroke 2010)

Colgan Air Flight 3407 Accident

On the hand, some plans may be slow to respond to the pilot's commands; complicating the piloting process, much like a sports car, for example, that under steers or a truck that over steers (Personal Communication, 2010). Bay contends that training on more than one plane of a particular model would prove to be a positive practice for airlines to implement.

Bay asserts that the following questions need to be answered regarding the cause of the crash of Flight 3407.

How much training and experience did the pilot/s have with this particular aircraft?

How many hours experience did the pilot/s have flying this particular craft?

Did a matter of pilot fatigue play a part in the incident?

Could alcohol have been a factor in the pilot's inability to "do the right thing"?

Were there any known defects with the plane?

Did any type mechanical malfunction occur?

On what date was…… [Read More]

Cleft Palate and Cleft Lip

Cleft lip / Cleft palate

Introduction to the disorder

When the upper lip and top of the mouth do not join successfully early in the pregnancy, a strange condition known as cleft lip/palate is said to have occurred. The lip and palate grow independently, so it is feasible for an infant to be conceived with just a cleft lip, or just a cleft palate, or a blend of both. When there is a gap or opening reaching out from the lip as far as up as the nose then it is a complete cleft lip. In some cases, some tissue stays underneath the nose, leaving a piece of the lip joined beneath the nose - this is referred to as an incomplete cleft lip. The roof of the mouth is comprised of two principle parts - a bony segment called the hard palate and a soft tissue / muscular part…… [Read More]

Physiological Effects of Endurance Training

Physiological Effects of Endurance Training

Endurance training produces many physiological changes, both during training and after the training period is complete. These changes are biochemical and also involve changes in the cardio-pulmonary system. The correct way to perform endurance training has been a subject of controversy in recent years. There are many differences in training methods. These differences and the effects of endurance training will be the subject of this research. The jury is still out as to what constitutes the perfect duration and intensity of training program.

Studies have shown that a focused training program can increase maximum oxygen intake by 15-30% over a three-month period (7) and that can increase to 50% if the training is sustained for over 2 years. The body makes many metabolic adaptations as well. These adaptations drop rapidly in the first few weeks after training is stopped (1).

Duration and Intensity of Different…… [Read More]

Fibromyalgia One Might Consider Fibromyalgia to Be

Fibromyalgia

One might consider fibromyalgia to be one of the most confounding conditions around today. It is debilitating. It results in several quality of life issues. The confounding aspect of this condition is that it is difficult to diagnose. It is also difficult to treat. Most treatment modalities today recourse to treating one or more specific symptoms -- but there is no treatment that can comprehensively treat all the symptoms. (NIAMS, 2004) More holistic treatment modes however, are being researched, explored and considered. Fibromyalgia often presents symptoms of other diseases. Essentially therefore, fibromyalgia is characterized by widespread pain that cannot be localized to any part of the body. It is also associated with fatigue and other specific (though not necessarily widespread) symptoms that will be discussed later in this work.

Fibromyalgia syndrome is often referred to in its abbreviation FMS. Some of the symptoms (though not all) enjoy significant overlap…… [Read More]

Perception How Does Depth Perception Occur in

Perception

How does depth perception occur in a person who gains sight after being congenital blind?

Depth perception is necessary for the ability to perform many tasks including driving, and many other activities. The ability to perceive the distance of objects is a complex process. hen people are born blind in one eye, regardless of the reason, they do not develop the ability to perceive depths. Their world is flat compared to that experienced by the rest of the world. hen that person undergoes surgery or other procedures to restore sight to the blind eye many of these patients are able to perceive depth. The ability to do this defies commonly held views on the connection between visual acuity, depth perception and motor development.

This research explores current research on depth perception and the development of depth perception. Studies in this area are limited to animal studies and those involving…… [Read More]

Exercise and Gymnast Injuries to

And a way to avoid injuries to the elbow, that is fairly obvious, is to use thicker landing mats, and to get expert training in how to fall properly. For males, injuries to the wrist have been identified as being caused by training on the pommel, because "the wrist is exposed to repetitive forces of up to twice body weight during this activity."

Exercises using the plyometric strategy are very useful for gymnasts; plyometric exercises are the "rapid deceleration and acceleration of muscles" that in turn help create a stretch-shortening cycle," according to www.specialolympics.org.These kinds of exercises train the muscles, and train the nervous system to carry out in an effective way the stretch-shortening cycle, which can improve the performance of a gymnast. Drills using plyometrics also help the athlete develop "rhythm, speed, power and even muscular endurance," the Special Olympics site explains. All plyometric exercises must be carried out…… [Read More]

Cardiac Cycle: Diastole and Systole Phases and Heart Disease

The objective of the research in this study is to examine the cardiac cycle from the anatomy and physiology perspective. Toward this end, literature in this area of inquiry, which for the purpose of this study is the cardiac cycle, is examined and reported.

Two Phases of the Cardiac Cycle

The work of Klabunde reports that the single cycle of cardiac activity may be divided into two primary phases stated to be those of: (1) the diastole phase; and (2) the systole phase. (Klabunde, 2012, p.1, p.1) Diastole is representative of the span of time when the "ventricles are relaxed…blood is passively flowing from the left atrium (LA) and right atrium (RA) into the left ventricle (LV) and right ventricle (RV), respectively." (Klabunde, 2012, p.1) The mitral and triscuspid or atrioventircular valves are reported to "separate the atria from the ventricles…… [Read More]

Steroid Use Controversies of the

e., their use of anabolic steroids (and whether they had ever been offered steroids), their involvement in power sports, appearance and eating problems, and problem behavior. Background information about the participants included their degree of urbanization, parental socioeconomic status and the region to which they belonged.

Analyses of the study's results show that the prevalence of steroid use among Norwegian youth was lower (lifetime use was 0.8% and 12 months prevalence was 0.3%) than in several other Western societies such as the U.S. (2.5% to 7%) and in Australia, Canada, Sweden and South Africa (2% to 3.5%). It also showed that AAS use was first and foremost associated with problem behavior (i.e., drug [marijuana] involvement and aggressive-type conduct problems). Its relation with power sports and appearance came in at second and third place respectively.

The study is, therefore, significant in highlighting the hitherto largely ignored area of problem behavior in…… [Read More]

Anabolic Steroid and Performance Enhancing Drug Use

Anabolic Steroid and Performance Enhancing Drug Use

Among High School Athletes

Anabolic steroid use has, at least in the past, been prevalent among major college and, especially, professional sports. Major League Baseball implemented a drug testing regimen very recently after backlash from fans made it an issue that the sport believed it had to listen to. The National Football League has a testing program that has been in place since 1989, and other sports have also begun programs to test for anabolic steroids and other performance enhancing drugs (PED) to ensure that there is a level playing field among all of their athletes. Unfortunately this testing has led to consequences for some athletes.

Some notable case of athletes being either stripped of honors or not being selected for honors because they acknowledged PED or steroid use have occurred in recent times. Lance Armstrong was recently stripped of all of his…… [Read More]

[hs130, section: ____ ]

I walked into my office at 8:00 AM with an empty mind. I was worried about the transmission that I needed to air in two days. When my boss asked me that morning about what the transmission would be, I lied and said, "Let that be a surprise!" I quickly logged online for ideas. Just then, I was interrupted by a man who wanted to speak to me. Annoyed at his persistent nagging, I grabbed my camera and decided to follow him to where he wanted to take me. During our ride, he asked me the most bizarre question, "can you film inside a patient? The doctors can't seem to understand what's going on in her body." My reaction was rather quick and loud, "Are you insane?" He pointed to a medium sized box in his backpack, "Whenever you're ready!"

He escorted me to…… [Read More]
