Electrical excitation of a muscle fiber. Skeletal muscle fibers (cells) can be stimulated either by amotor neuron in the body or by a voltage stimulator in the lab. Stimulation given by either method results in a depolarization of the sarcolemma. If the depolarization reaches threshold, an action potential (electrical signal) is initiated.
