During twitch contraction, the latent period is directly followed by the contraction period. Group of answer choicesTrueFalse

Answer:

True

Explanation:

During a twitch contraction in muscle physiology, there are distinct phases that occur sequentially after a stimulus is applied. The latent period is the brief interval of time after a stimulus is given but before the muscle contracts. This delay occurs due to the physiological processes that take place, including the release of calcium ions from the sarcoplasmic reticulum and the formation of cross-bridges between actin and myosin filaments.

Once the latent period ends, the contraction period begins. This is when the muscle fibers actively shorten, resulting in muscle contraction. The contraction phase manifests as the muscle generates its maximum tension. Following this contraction phase, there is a relaxation period where the muscle fibers return to their resting state.

In summary, the statement is true because the latent period is indeed directly followed by the contraction period in a twitch contraction sequence.
