Question

Quizplus · Accepted Answer

The refractory period is a temporary period after a muscle fiber has contracted in which it is unable to respond to stimuli, as the muscle is attempting to reset itself to its resting state. The latent period is the brief period between the initiation of a muscle stimulation and the muscle contraction. The relaxation period is the period when the muscle is returning to its resting state after contraction. The fatigue period is the state of exhaustion of a muscle due to prolonged contraction or repetitive stimulation.
