Small motor units permit very fine motor control of the muscle. The best example in humans is the small motor units of the extraocular eye muscles that move the eyeballs. The size of a motor unit varies from just a few fibers in the eye muscles (precise movements) to over a thousand fibers in the large leg muscles (powerful movements). A skeletal muscle twitch is a contractile, or mechanical, response to a single action potential. About MyAccess. Although tension development in response to an whole muscle contraction. The number of these muscle fibers can vary from 1 or 2 to 1000. Typical muscles are controlled by around 100 large motor neurons. Most mature extrafusal skeletal muscle fibers in mammals are innervated by only a single motor neuron.
