Motor unit summation or spatial summation is the recruitment of additional motor units within a muscle to develop more force. Motor unit summation occurs until sufficient force is developed within ...
Motor unit summation or spatial summation is the recruitment of additional motor units within a muscle to develop more force. Motor unit summation occurs until sufficient force is developed within ...
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 ...
Motor Unit Recruitment. A motor unit contains one motor (efferent) neuron and all of the skeletal muscle fibers (cells) it stimulates. A single muscle contraction is the result of groups of motor units coordinating together. Answer and Explanation: 1
