Describe the structure of a motor unit
WebMotor unit recruitment is the process by which different motor units are activated to produce a given level and type of muscle contraction. At minimal levels of muscle contraction (innervation), muscle force is graded by changes in firing rate (rate coding) of individual motoneurons (MNs). ...

WebA motor unit comprises a motor neuron and the muscle fibers it innervates, illustrated here by motor neuron A1. The motor neurons innervating one muscle are usually clustered into an elongated motor nucleus that may extend over one to four segments within the ventral spinal cord. The axons from a motor nucleus exit the spinal cord in several ... WebA motor unit consists of a motoneuron and the muscle fibers it innervates. Motor units possess different properties and are classified as Type I (slow, fatigue resistant, their motoneurons are relatively small), Type IIA (fast but fatigue resistant), and Type IIX (fast with low resistance to fatigue). Fast motor units have motoneurons of ...
