A muscle twitch produces external tension and moves an object by shortening the muscles during the _____ phase.

Question

Quizplus · Accepted Answer

During the contraction phase of a muscle twitch, the muscle fibers actively shorten, generating tension and movement in the associated structure or object. The latent phase precedes the contraction, during which the muscle prepares for contraction by releasing calcium ions, and the relaxation phase follows, during which the muscle fibers lengthen and return to their original state. The twitch phase specifically refers to the brief period of muscle activation and tension during a muscle twitch. The reload phase is not a recognized phase of muscle twitching.
