During the latent period of a muscle twitch
WebA single muscle twitch has three components. The latent period, or lag phase, the contraction phase, and the relaxation phase. The latent period is a short delay (1-2 msec) from the time when the action potential reaches the muscle until tension can be observed in the muscle. What is meant by the term latent period? Listen to pronunciation. Web1. Latent period- the period of time that elapses between the generation of an action potential in a muscle cell and the start of muscle contraction 2. Contraction phase- …

WebThe other three phases of a skeletal muscle twitch are the latent period, the contraction phase, and the relaxation phase. The latent period is when the muscle cell is preparing … WebThe first phase is the latent period, during which the action potential is being propagated along the sarcolemma and Ca ++ ions are released from the SR. This is the phase during which excitation and contraction are being coupled but contraction has yet to occur. The contraction phase occurs next.
WebThe latent period is the time required for the release of Ca 2+. The contraction period represents the time during actual muscle contraction. The relaxation period is the time during which Ca 2+ are returned to the … Weba twitch is. one contractile response to a single action potential. what is the period of time that elapses between the generation of an AP and the start of muscle tension …

[This is not the same as the absolute refractory period, the even briefer period when the sarcolemma is depolarized and cannot be stimulated.
