What are the 3 types of muscle? - Answer Cardiac-striated Skeletal-striated Smooth-not striated What is a muscle antagonism? - Answer Flexor extensor pairs (bicep/tricep) What is the organization of a sarcomere? - Answer Z disks-set border for sarcomere I Band- a region containing only thin filament (actin) A Band- the area that has both thin and thick fibers H Zone-the area consisting of only thick fibers How does muscle cross-bridging work? - Answer Myosin reaches over and binds to an actin strand What are the three major steps leading up to muscle contraction? - Answer Release, Binding, Powerstroke (maybe, unsure) Explain excitation contraction coupling - Answer The elctrical stimulation of muscle fibers due to an action potential causes the binding of Ca+2 and causes muscle contraction Explain the contraction-relaxation cycle - Answer Ca ions bind and cause muscle contraction. Ions are removed via ATP and the muscle fiber relaxes What part of sarcomere contraction requires ATP? - Answer Relaxation What actions required for skeletal muscle contraction require ATP (3 actions)? - Answer
