Quizplus · Accepted Answer

The delay between the time a stimulus is applied and the time the muscle responds is called the latent period. This is the time it takes for the action potential to reach the muscle fibers and for the calcium ions to be released and initiate the contraction. The refractory period refers to a period of temporary insensitivity to further stimulation that occurs after a nerve or muscle has been stimulated. The relaxation, contraction, and recovery periods all refer to different phases of muscle contraction and relaxation.
