During the latent period of a muscle twitch
WebA twitch occurs when one muscle fiber contracts in response to a command (stimulus) by the nervous system. The time between the activation of a motor neuron until the muscle contraction occurs is called the lag phase (sometimes called the latent phase). During … Muscle contraction remains as long as Ca +2 is abundant in sarcoplasm. Types of … 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 …
