WebA motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the … WebThe functional properties of nerve and muscle are matched in such a way as to maximize efficiency of the motor unit. This matching is in large measure determined by the neuron which, by virtue of impulse and trophic activities, controls the metabolic and physiologic attributes of the muscle fibers it innervates.
WebA motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.
