Question

Which of the following statements best summarizes excitation-contraction coupling?

Answer 1

Answer:

C. A series of events in which an electrical stimulues is conveyed to a muscle fiber to enact contraction.

Explanation:

The excitation-contraction coupling is the physiological process that converts an electrical stimulus to a mechanical response; it is the action potential generated in the sarcolemma and the start of a muscle contraction. Electrical signals called action potentials travel through the neuron's axon, which branches through the muscle and connects individuals fibers at a neuromuscular junction.
