ich of the following is the correct order for the phases of a muscle twitch?

a) latent, contraction, relaxation

b) latent, relaxation, contraction

c) contraction, relaxation, latent

Explanation:

A muscle twitch has three phases. The latent phase is when the muscle is preparing for contraction (like receiving the nerve signal). Then comes the contraction phase where the muscle actually shortens. Finally, the relaxation phase occurs when the muscle returns to its resting state.
