Document Summary
Exercise 2: skeletal muscle physiology: activity 2: the effect of stimulus voltage on skeletal muscle contraction lab. You scored 50% by answering 2 out of 4 questions correctly: skeletal muscle fibers are innervated (stimulated) by. You correctly answered: c. motor neurons: a single action potential propagating down a motor axon results in. Your answer : c. a single action potential and several contractile events in the muscle fibers it innervates. Correct answer: d. a single action potential and a single contractile event in the muscle fibers it innervates: in resting skeletal muscle, calcium is stored in. Correct answer: c. the sarcoplasmic reticulum: during the latent period for an isometric contraction. You correctly answered: c. the cellular events involved in excitation-contraction coupling occur. Your answer : c. the active force will first increase and then plateau at some maximal value as the stimulus voltage increases. 0. 00 g; there was no activation of skeletal muscle fibers by this stimulus.
