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.
A muscle fiber contracts in an all-or-none fashion. There is a slight latent period that occurs between when the stimulus arrives at the muscle and when the muscle contracts. Muscles will add motor units to a contraction, increasing the overall force of contraction.When a person is fully at rest, none of her muscles are contracting.here is a slight latent period that occurs between when the stimulus arrives at the muscle and when the muscle contracts.
