The biological significance of motor pool organization is in the fact that motor pools with many neurons produce finer movements. For example, the motor unit of muscles in the torso will control more muscle fibers and so cannot discriminate and selectively contract one particular fiber over another. In finger s, the muscles will have a higher proportion of neurons innervating similar muscles, thus allowing for more precise movements.

The motor impulses originates in the Giant pyramidal cells or Betz cells of the motor area i.e. precentral gyrus of cerebral cortex. These are the upper motor neurons UMN of the corticospinal tract. The axon s of these cells pass in the depth of the cerebral cortex to the Corona radiata and then to the Internal Capsule passing through the posterior branch of internal capsule and continue to descend in the Midbrain and the Medulla Oblongata . In the lower part of Medulla oblongata 80 to 85 of these fibers decussate pass to the opposite side and descend in the White matter of the Lateral funiculus of the spinal cord on the opposite side. The remaining 15 to 20 pass to the same side. Fibers for the extremities Limb anatomy limb s pass 100 to the opposite side.

image Servomotor.jpg thumb right 200px Industrial servomotor br The grey green cylinder is the Brush electric brush type DC motor . The black section at the bottom contains the Epicyclic gearing planetary Reduction drive reduction gear , and the black object on top of the motor is the optical rotary encoder for position feedback. This is the steering actuator of a large robot vehicle. A servomotor is a motor which forms part of a servomechanism . The servomotor is paired with some type of encoder to provide position speed feedback. This feedback loop is used to provide precise control of the mechanical degree of freedom driven by the motor. A servomechanism may or may not use a servomotor. For example, a household furnace controlled by a thermostat is a servomechanism, because of the feedback and resulting error signal, yet there is no motor being controlled directly by the servomechanism. Servomotors are not the only means of providing precise control of motor output. A common alternative is a stepper motor . In a stepper motor, the input command specifies the desired angle of rotation, and the controller provides the corresponding sequence of commutations without the use of any feedback about the position of the system being driven.

A motor goal is a neurally planned motor outcome that is used to organize motor control . Motor goals are experimentally shown to exist since planned movements can when disrupted adjust to achieve their planned outcome. If, for example, a person makes a movement of their hand to touch or grasp something and unexpected their arm is pushed their brain automatically reorganizes the movement so it so achieves its intended aim. This also occurs if an arm is perturbed which results in an automatic correction that enables it to fulfill its planned spatial temporal target. ref Haggard P. Wing A. 1995 .
