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.
What happens at the neuromuscular junction? One motor neuron (nerve cell) may stimulate a few muscle cells or hundreds of them, depending on the particular muscle and the work it does. One neuron and all the skeletal muscle cells it stimulates are a motor unit. When a long threadlike extension of the neuron, called the nerve fiber or axon, reaches the muscle, it branches into a number of axon terminals, each of which forms junctions with the sarcolemma of a different muscle cell.
