[QUOTE="BigTex, post: 247643, member: 43589"] WOW! It could also be used when doing tests in exercise science. I still remember this from my masters degree exercise physiology final -[B] Explain the sliding filament theory:[/B] [I]The sliding filament theory is a scientific explanation of how muscles generate force and contract. It is widely accepted by scientists and forms the basis for our understanding of muscle physiology. According to the sliding filament theory, muscle contraction occurs when the thin filaments (made of actin) slide past the thick filaments (made of myosin) within muscle fibers, resulting in the shortening of the muscle. The process of muscle contraction is initiated by a signal from the nervous system, which causes the release of calcium ions within the muscle fibers. These calcium ions bind to the protein complex called troponin, which is located on the thin filaments. As the troponin binds with calcium ions, it undergoes a conformational change, which causes the tropomyosin (a protein that covers the actin binding sites) to move away from the myosin-binding sites on the actin. This exposes the binding sites on the actin, allowing the myosin heads to bind to them. Once the myosin heads bind to the actin, they undergo a conformational change, which pulls the thin filaments towards the center of the sarcomere (the functional unit of muscle fibers). This shortens the sarcomere, resulting in the overall contraction of the muscle fiber. This process is repeated numerous times as the myosin heads continue to bind to the actin and pull the thin filaments towards the center of the sarcomere until the muscle is fully contracted. The sliding filament theory provides a detailed explanation of the molecular mechanisms that underlie muscle contraction an[/I]d helps scientists understand the physiological basis of muscular diseases and disorders. Holy crap, I figure I could write a book using this. Just tried something else......it writes code! I do see a tint of biase in some of the stuff written. [/QUOTE]
