Document Summary

8: list the principal functions of skeletal muscles. Heat production muscle is a major metabolic muscle: list the principal proteins contained in skeletal muscle. Type ii fast twitch bridges cycle less rapidly: take approx. 110 microseconds to reach peak tension: more oxidative fibers, slow form myosin atpase atp split less rapidly, cross, fast form myosin atpase atp split more rapidly, cross, take approx. 50 microseconds to reach peak tension: less oxidative fibers, type iia, iix (in humans), iib(in animals) bridges cycle more rapidly, outline the contractile process. Use a step-by-step format illustrating the entire process, beginning with the nerve impulse reaching the neuromuscular junction. More na come in than k leaves causes depolarization and we get an end-plate potential: end plate potential will eventually reach threshold and trigger an action potential. Terminal cisternae holds calcium: on t-tubule there is a voltage sensitive protein that is connected to release channel on sr.
