Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period. Skeletal muscle fibers are the individual cells that are bound together in fascicles. Many fascicles are bound together to make a muscle. A motor unit consists of a motor neuron and all of the muscle fibers in innervates. A skeletal muscle twitch is a mechanical response to a single action potential. During this experiment, we used an electrical stimulus to mimic the contractions of skeletal muscles. It is done in vitro to produce in vivo results.
