Question

which of the following is the correct sequence of steps involved in a muscle contraction? multiple choice excitation, coupling, contraction, and relaxation coupling, excitation, contraction, and relaxation relaxation excitation, coupling, and contraction contraction, relaxation, coupling, and excitation

Explanation:

Muscle contraction starts with nerve - impulse induced excitation. Then, the excitation - contraction coupling process occurs, which links the electrical signal to the mechanical response. After that, the muscle contracts, and finally, it relaxes.

Answer:

A. Excitation, coupling, contraction, and relaxation
