Nettet1. jan. 2004 · The central nervous system controls muscle force by varying the activity of the motor units that comprise the muscle. The motor unit consists of a motor neuron in the ventral horn of the spinal cord, its axon, and the muscle fibers that the axon innervates (Liddell and Sherrington 1925, Sherrington 1925; Fig. 1).The muscle fibers belonging to … NettetA motor unit is defined as a motoneuron, its axon, and all the muscle fibers which that axon innervates (Burke and Edgerton, 1975), although the original definition included only the axon and adjunct muscle fibers (Creed, Denny-Brown, Eccles, Liddell, and Sherrington, 1932; Liddell and Sherrington, 1925).

Note, mitigating noise at the source is usually the best option. NettetMotor unit. Motor unit is the functional segment of skeletal muscles. A motor unit contains two main components: a single different motor neuron (it is a neuron that carries signals away from the central nervous system) and all the muscle fibres. Motor unit is made up of a single neuron that makes a group of skeletal muscles. tous anticovid wikipedia
