    socratic.org/questions/what-is-a-motor-unit

    Within a muscle, the muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates. The size of the unit can involve only a few fibers for fine movement to huge numbers for gross movement such as what occurs in walking. The force generated by muscles to lift a feather is much less than the force required to ...
