Document Summary
Review questions (cid:120) what is the m line? (cid:120) what is a sarcomere? (cid:120) name 2 important features of the myosin globular head: atpase, actin-binding site (cid:120) Identify 3 broad types of muscle fibres: type i, type iia, type iib (cid:120) which is more resistant to fatigue, type i since it is most reliant on glucose oxidation (cid:120) In order for active contraction to occur, you need an optimal overlap of thick and thin filaments for cross bridges to form. If z discs are too close, the sarcomere has nowhere to go (mechanical interference of contractile elements) Instead, power is the time derivative of work, and relates to velocity (cid:120) how does skeletal muscle act on a limb? (cid:120) what part of the arm serves as a fulcrum: elbow. Identify 2 classification schemes for smooth muscles (cid:120) (cid:120) how do multi- and unitary smooth muscle differ: multi e. g. iris.
