Muscular dystrophy (MD) is a group of genetic diseases involving progressive weakness and degeneration of the muscles that control movement. In some forms of MD‚ the heart muscles and other involuntary muscles‚ as well as other organs‚ are affected. There are 9 distinct types of MD. Myotonic MD is the most common form among adults‚ while Duchenne MD is the most common form among children (it affects only boys). Some are severe diseases at birth that lead to early death. Others follow very slow progressive

Homeostasis Homeostasis Is a technical term for the process of maintain a constant internal environment despite external changes. The internal environment‚ compromises; blood‚ tissue fluid‚ body cell contents and all the metabolic processes taking place. Constant in this instance is not absolute or fixed it is much more flexible and dynamic as it refers to the physical and chemical composition being kept within a limited range or variables for maximum efficiency‚ well-being of the whole body and

Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the blood can supply. At this point the muscle is forced

equate large muscles with strength‚ that is not necessarily so. Strength is not directly proportional to the size of a muscle. First‚ you need to decide which muscles you want to strengthen‚ then find the best way to exercise those muscles so they will respond with increased strength. Then keep increasing the weight load to challenge the muscles. For instance‚ add 1 pound now and another pound in a month‚ and so on. The more you load the muscles‚ the stronger they will become. Muscles respond quickly

human body? To ensure that fluid levels inside and outside the cell are balanced. How does your electrolyte work in the functioning of nerves and muscles? Like athletes when they workout they lose salt by sweating. That’s why they try to contain salt before they work and after‚ to avoid cramps and such. The cramping effects the nerves and muscles‚ because they begin to shut down. As the salt in your body fades away. What are some of the specific health problems that can arise from an imbalance

Muscle and joint actions both affect the performance of a discus-athlete. Various types of joint actions and muscular actions can take place once when the movement is executed by the athlete. As an example‚ a discus-thrower usually activates the horizontal abduction and the horizontal adduction during the preparation or execution phases of his/her throw. The ground contact of the discus-thrower is very important as it keeps the thrower’s center of gravity station within his/her strongest point of

Staying active means keeping your body functioning at a high level. Regular exercise will maintain the performance of your lungs and heart to most efficiently burn off excess calories and keep your weight under control. Exercise will also improve muscle strength‚ increase joint flexibility and improve endurance. Another main benefit of physical activity is that it decreases the risk of heart disease‚ the leading cause of death in America. Additionally‚ it

Table 1 was our observation for the control group‚ or the ChR2- as we called it. Living up to its name‚ the larvae from this plate did not contract as we increased the MRR‚ and continued to move. Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times
