¶ … Skeletal Muscle
Academic Institution
The most important skeletal muscle in the human body is the diaphragm. The diaphragm is the large dome shaped muscle that functions as the main muscle involved in respiration (Drake, Vogl, & Mitchell, 2009; Moore, 2014). Of course the reason that this muscle is the most important skeletal muscle is that it is involved in breathing and without oxygen the organism would perish in only a few moments. Thus, before any other muscle or organ can perform for any length of time they need to receive oxygen.
The lungs are surrounded by the rib cage with the diaphragm forming the floor of the thoracic cavity. The entire diaphragm separates the chest cavity (thoracic cavity) from the abdominal cavity. There are openings in the diaphragm that allow the descending aorta, inferior vena cava, the esophagus, and the phrenic and vagus nerves to pass between the thoracic cavity and the abdominal cavity (Drake et al., 2009). Anatomists generally divide the diaphragm into two parts: (1) the peripheral muscle, and (2) the central tendon (Drake et al., 2009).
The peripheral muscle of the diaphragm is composed of a large number of radial muscle fibers that originate...
" (Walker, 1999) the gas crisis caused that particular market sector to almost completely vanish, and the need for increased efficiency shifted power in the automotive industry away from designers and into the hands of engineers. Detroit tried one last time to introduce small cars to the American public, but this attempt was far less successful than all others before it. GM created the Chevrolet Vega, and Ford had the
Each muscle of the body has a specific function and purpose, it is important to be able to know what muscle one is working on, the ability of that specific muscle, as well as the limitations of that specific muscle. Understanding how parts of the body (specifically bones) and how they relate to muscles allow personal trainers the ability to hone in on particular muscle groups and aid clients
In a comparative study, Klein and colleagues (1994) studied the overall fat metabolism ratios for endurance-trained and untrained men during low-intensity exercise routines. They sample a total of 10 men, 5 who were endurance-trained athletes and 5 who were untrained. They started off by calculating and analyzing the overall lipid activities and muscle activities while all 10 subjects were resting before the exercise routines began. They also calculated the free
2. A functional syncytium a single, enormous muscle cell. 3. The fascia adherens component. 4. The aorta has a tunica media dominated by elastic tissue. The elasticity conferred by elastin allows these elastic arteries to smooth out the sharp changes in blood pressure resulting from the pumping heart. 5. An artery would have a larger lumen than its corresponding vein. With such relatively thin walls, veins tend to appear flattened or collapsed in
Learning Memory is an important construct of human brain which performs a significant role in each and every activity of life. It is interesting to mention that brain is also a muscle and its energy can be increased by using it. There are many tactics found in literature and everyday practises to sharpen memory skills. However, the most effective technique is to play games which appear interesting to the players and
Personal Development The important part of creating a healthy lifestyle for yourself is to create a plan that makes sense both for your body and your mental makeup, and stick with it to see if it really works. Being in a long-term relationship requires attention to intimate details. The motivation to engage in sexual intimacy can fade with time, even if you love the person. This is "the most common
