Physiology & the Orange as I Tune
Pages: 2 Words: 778

Physiology & the Orange
As I tune in to "my orange," I find that it is difficult to separate the sensory input that I am experiencing. My mind seems to put integration on automatic pilot. Before I close my eyes, I find my visual sense to be dominant. I know that I tend to be a visually-oriented person anyway, so this is not really a surprise. But in my attempts to deal with each sensation separately, it is readily apparent that vision stays in the forefront of my awareness. I know from my reading that the brainstem receives information from my eyes and ears and then sends the sensations along to the midbrain.

Once I close my eyes, it becomes easier to focus on the sensations that my fingers and hands are generating as I manipulate the orange. I am aware of the heft and roundness of the fruit, and the texture…...

Body Systems Involved in Eating a Snack

The first thing I do when eating a snack is to prepare it. In this case, I reach into the cabinet above me and grab a bag of potato chips. I read the label and make sure they are plain chips, because I do not like flavored chips. When I am satisfied they are the type of chip I like, I break open the seal of the bag. I immediately smell the chips when I open the seal. The smell is familiar: oily, salty, and potato-ey. Still standing, I reach one hand into the bag of chips. My fingers feel all the salt granules and the distinct shape of the thinly sliced crisps. The edges of the crisps are rough but not sharp. I put one chip into my mouth and begin to chew. The initial flavors are salty, and then that gives way…...

Pages: 3 Words: 917

In an acute shock situation, the body shuts down many of its functions in the interest of addressing the patient's most-urgent problem.
In addition to reduced kidney function, the patient's brain function slows down; she may appear lethargic, have difficulty talking, and eventually lapse into a coma. This is due to the body's diverting blood supply from the brain, which typically takes 20% of oxygen and nutrition, to other areas which require it most.

The woman's broken cells will put out markers for tissue injury: in the case of the liver, the SGPT and SGOT enzymes will be elevated, indicating liver damage. General enzyme levels indicating systemic injury will also climb, including myoglobin, various tissue factor antigens, endotoxins and a series of other enzymes which are released upon cell destruction. If the initial concern was the spleen, kidney and liver, it may also make sense for the attending ER physician to…...

Physiology of Emotions
Varying Theories on the Physiology of Emotions

In their theory, "How Emotion Shapes Behavior: Feedback, Anticipation, and eflection, ather Than Direct Causation," Baumeister, Vohs, DeWall and Zhang show how the secondary function of emotions is much more important to humans than their initial response to an emotion. Emotions in response to stimuli provoke actions that usually begin too late to effectively react to the stimuli. Thus, it makes more sense to consider the function of emotions as part of a learning process than it does to imagine their value rests with the initial human response. Human emotion is studied as a feedback system that shapes current and future behaviors based on processing prior actions and reactions motivated by emotions. We need this feedback system to successfully function in such complex social and cultural systems. For example, if one is in a public place and moved to anger by another…...

The plaintiff sustained life-changing and debilitating injuries in the form of skin cancer that could have also proven fatal had it not been diagnosed in time to treat. There is still no guarantee that the cancer will not recur and the plaintiff will now have to endure that grave uncertainty for the rest of his life.
The employer benefited tremendously from the labor of this employee and it had an affirmative duty to provide the necessary information and forms of protection against solar radiation that could have easily prevented these harms. In light of the tremendous danger and cost of treating skin cancer in comparison to the relative small cost of providing simple precautions and protocols to protect it employees, the employer had a duty to protect the health and welfare of its employees.

These indications then proceed to the neuromuscular connections of skeletal muscles. From there, acetylcholine is released from the axon terminal knobs of alpha motor neurons and received by postsynaptic receptors of muscles, thereby communicating the stimulus to contract muscle fibers (Ihlen & Vereijken, 2010).
Psychological Influences

esearch on patient's brains scanned by Positron Emmision Tomography have designated that the kind of thoughts people have influence the balance of brain chemicals, so by learning to think more positively and sensibly one can influence brain chemistry in a positive way, but other factors like an unloved, unsupported childhood can influence brain chemistry and physiology in such a way that it makes people less able to cope with stress in adulthood. If people think mainly negatively their brains secrete chemicals that can undermine their psychological and physiological health, whereas if they think more positively they can cause chemicals to be secreted that boost their…...

Therefore, in cases unrelated to ileocecal valve malfunction, large distal bowel obstruction is a direct function of LaPlace's Law at the area of the cecum. For the same mechanical reason, the most frequent location of colonic perforation is also at the cecum because it is the area of the largest diameter, and therefore, most susceptible to rupture in comparison to areas smaller in diameter.
11. What are the major types of movement of small intestine?

The first major type of movement in the small intestine is peristalsis. The second major type of movement in the small intestine are discrete clustered contractions, which are comparatively small movements. The third type of major movement in the small intestine is giant migrating contractions, which are larger versions of peristaltic contractions believed to serve a bacterial cleansing purpose.

Physiology - Effects of Moderate
Pages: 4 Words: 1186

Therefore, understanding the ways in which insulin resistance can be counteracted is critical toward developing strategies to help individuals with insulin resistance issues. Kaoru et al. explain that increasing fatty acid utilization fights insulin resistance, and that exercise is known to increase utilization (109). The question mark, as the authors explain, is how much exercise and at what level is required in order to facilitate fatty acid utilization. Therefore the rationale for designing a study to probe this question was well founded.
The hypothesis of the study was similarly well-structured. As already mentioned, the study was designed to test the hypothesis that fatty acids are available for utilization in the body even following short-term exercise at low levels of intensity (109). This is a positive hypothesis, one that is designed to demonstrate a conclusion the authors are interested in finding. The study could have, in theory, been designed in an…...

Physiology of Nephrotic Syndrome
Pages: 11 Words: 3591

Nephrotic Syndrome is not a disease. It is a condition that is characterized by damaged glomeruli in the kidney. This damage might be caused by one or more disease. These diseases can be related to the kidney as in Familial Focal Segmental Glomerulosclerosis, abbreviated FFGS or membranous nephropathy. Or it can present from relatively distantly related diseases such as heart diseases, hypertension, diabetes and lupus. The types of diseases that cause nephrotic syndrome also vary with age. Some cases can be corrected with properly prescribed medication, despite some side effects. In more serious cases, kidney failure can occur. Regular dialysis and ultimately, transplantation may be required. Nephrotic Syndrome can cause damage to (or arise from damage to) the glomeruli, which affects it's function of filtering out waste matter and excess water that is converted into urine. Nephrotic syndrome is identified from symptoms known as proteinuria, hematuria and edema. The first…...

Evolution of Organisms

For millions of years earth has gone under tremendous changes. This rapid change in environment, landscape and temperature alters the intact system and for surviving this change, a steady modification in living organisms occurs for adaption to surrounding environment. This change is never over night nor does it occur suddenly in newborns, it takes generations to evolve a new feature or characteristic. This adaption is not only in mammals but can also occur in plants and microscopic organisms; plants developed the process of photosynthesis in order to survive in oxygen abundant environment and micro-organisms being not used to access of oxygen either went extinct or formed symbiotic association with oxygen for survival.

The rule of survival of the fittest as determined by nature also applies to all living beings inhabiting earth. A simple example would be a breed of heavy coated sheep living in extreme hot conditions can…...

Cross-Eyed Flatworm Physiology
Pages: 3 Words: 977

Organism Physiology
The Planarian or "cross-eyed flatworm" is a relatively simple invertebrate organism, belonging to the animal kingdom and the phylum of Platyhelminthes which covers all flatworms. The phylum of Platyhelminthes contains four separate classes: three of these cover parasitic forms of flatworm that live inside other organisms (like the famous tapeworm). The fourth class, Turbellaria, includes all non-parasitic flatworms. One of these is the Planarian, which exists in a number of different genus and species: our diagram is derived from the standard Planarian used for biology students, Girardia Tigrina. A close examination of the structures and functions of the main organs found in this simple organism can explain how the Planarian has evolved physiologically to become suited to its environment.

The first organ to consider in the Planarian is not an internal one. The epidermis, or outer skin layer, of the Planarian (numbered 4 on the diagram above) is a perfect…...

Atkins Diet Physiology Metabolic or
Pages: 5 Words: 2083

For obese individuals on the Atkins diet, a moderate exercise program that allows the body to burn fat rather than glycogen can be beneficial, since they would be able to exercise longer. For trained athletes, a higher level of exercise at a longer duration is possible, since the body's threshold for the change to using glycogen as ATP is higher.
Thus, our results that obese individuals on that Atkins diet who participate in moderate activity are able to exercise for longer periods of time is supported.

In conclusion, our results indicated that weight loss in our subjects was caused from a negative energy balance, rather than metabolic advantage. The Atkins diet works well not because of a lowered carbohydrate intake, but because of a lowered overall food and caloric intake. This lower level of food intake in turn leads to a higher ratio between energy output, and energy intake. These results…...

Project Management, Sustainability and hole Lifecycle Thinking
Application of Anatomy and Physiology when Performing Direct Patient Care

Scenario: A patient suffering from the following conditions requires direct patient care:

Urosepsis (Urinary tract infection)

Acute Gouty arthritis (Gout)

Cardiac dysrhythmias (Irregular heartbeat)

Hypertensive renal disease (Kidney damage caused by chronic high blood pressure)

DM Type II (Type II diabetes)

Bipolar (Bipolar disorder)

Derangement of joint (Internal joint damage caused by previous trauma)

Contracture joint (Permanent shortening and contraction of joint)

Dental condition (Missing all but four front teeth)

The presence of urosepsis in a patient already suffering from the chronic condition of Type II diabetes is an immediate concern. Diabetes causes many of the predisposing factors, including poor glycemic control, high urinary glucose, and increased bacterial adherence to uroepithelial cells, which are known to cause a variety of severe complications associated with urosepsis. This situation requires immediate treatment of the urinary tract infection through the administration of appropriate antibiotics to assure that the…...

Cushing's Disease Anatomy and Physiology
Pages: 2 Words: 929

Cushing's disease, as well as Cushing's syndrome, is caused by the overproduction of something called cortisol. Cortisol is "a normal hormone produced in the outer portion, or cortex, of the adrenal glands" (Margulies). hether your body naturally overproduces this hormone, or your body receives too much cortisol in steroid medications used as treatment for other diseases, it can lead to development of Cushing's disease.
In normal function, cortisol helps the body respond to changes and to stressors. Its normal functions include the mobilization of nutrients, modifying the body's response to inflammation, getting the liver to raise blood sugar levels, and regulating the amount of water in the body (Margulies). Adrenocorticotrophic hormone (ACTH for short) is made by the pituitary gland, and regulates cortisol production. Overproduction of cortisol, or taking in excess amounts via medications causes significant changes in "all of the tissues and organs of the body" (Margulies). The culmination of…...

Age can have a significant impact on diabetes management in older adults due to various physiological and psychosocial factors.

Physiologically, as individuals age, their body's ability to regulate blood sugar levels may decrease. This can make it more challenging for older adults to control their diabetes and maintain stable blood glucose levels. Additionally, older adults may be more prone to other age-related health issues such as cognitive impairment or mobility issues, which can make it difficult for them to consistently monitor and manage their diabetes.

Psychosocially, older adults may also face unique challenges when it comes to diabetes management. For example,....
