Question

Quizplus · Accepted Answer

The delay between the application of the stimulus and the response of the muscle is called the latent period. During this period, there is no visible contraction of the muscle, as the muscle cells are being stimulated to contract but have not yet responded. Once the latent period is over, the muscle enters the contraction period, which is characterized by visible muscle contractions. The relaxation period follows the contraction period, during which the muscle returns to its resting state. The refractory period refers to a brief period of time after a neuron has fired an action potential where it is unable to fire another action potential.
