How motor units work

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). At higher … Web10.4.2c- Motor Unit: A motor unit is a single motor neuron and the muscle fibers innervated by that neuron. The size of a motor unit dictates its function.

In a rotational system torque (t) - which consists of force and radius - replaces force (F), and distance (d) becomes the angle through which the torque acts. This means work = tθ, where θ is the angle. In the case of an electric motor, θ is 360-deg or one complete rotation.
