During the latent period of a muscle twitch
WebSep 10, 2024 · A Myogram of a Muscle Twitch A single muscle twitch has a latent period, a contraction phase when tension increases, and a relaxation phase when tension decreases. During the latent period, the action potential is being propagated along the sarcolemma. Does the muscle visibly shorten during the latent period? WebEach twitch undergoes three phases. The first phase is the latent period, during which the action potential is being propagated along the sarcolemma and Ca ++ ions are released …
