Lab #9: Muscle Physiology p.3 Muscle Twitch Parameters A twitch is a muscle contraction that occurs in response to a single, rapid stimulus that evokes a single, isolated action potential in a muscle fiber.
Contractions happen when actin filaments actually slide over myosin filaments. This slide causes a change in the shape of the muscle cells producing movement, which is considered a muscle contraction. Depending on the muscle and the intended outcome of the contraction, muscles can either lengthen or shorten.nstead, a muscle contraction of smooth or cardiac muscle is initiated within the organ itself. Within the digestive system, the introduction of food is what causes the contractions to move the food through the system.
