WebA motor unit is made up of a motor neuron and the skeletal muscle fibers innervated by that motor neuron's axonal terminals. Describe excitation-contraction coupling in a skeletal muscle fiber-In the absence of Ca+2, tropomyosin blocks myosin binding sites on actin Webskeletal muscle fibers from one type to another. It appears that muscle fiber types are determined embryologically by the type of neuron that innervates the muscle fiber. The default muscle appears to be slow, type I fibers. If a muscle is innervated by a small neuron that muscle fiber will remain slow, whereas large myelinated fibers
