The sequence of events leading from the nerve impulse to muscle contraction is called _____________.
A)excitatory muscle contraction
B)depolarization of the T-tubules
C)excitation-contraction coupling
D)None of the above answers are correct

Question

Quizplus · Accepted Answer

Excitation-contraction coupling refers to the series of events that occur between the electrical stimulation (nerve impulse) of a muscle fiber and the contraction of the muscle fiber. This process includes the release of calcium ions from the sarcoplasmic reticulum, binding of calcium ions to troponin on the thin filaments, movement of tropomyosin to expose binding sites on actin, formation of cross-bridges between actin and myosin, and sliding of filaments to cause muscle contraction.
