The action potential of skeletal muscle                 A. is not essential for contraction.                 B. is longer than the action potential of cardiac muscle.                 C. has a prolonged plateau phase.                 D. causes the immediate uptake of calcium ions into the lateral sacs of the sarcoplasmic reticulum.                 E. spreads inward to all parts of the muscle via the T tubules.
Botulism toxin inhibits the release of acetylcholine at the neuromuscular junctions. What effect does this have on the muscle activity? a. Muscles will contract continuously. b. Muscles will contract sporadically, without conscious control. c. Muscles will not contract because they will not receive nerve stimulation. d. There will be no effect on muscle activity
Which of the following is true?   A. Muscle fibers either will contract with all the force possible under existing conditions or will not contract at all. B. Skeletal muscles can contract with varying degrees of strength given different circumstances. C. Muscle length does not have an effect on contractile strength. D. Metabolic condition of the myocyte does not have an effect on contractile strength.
