In this chapter we discuss the evaluation of the motor systems, that is the systems involved in generation and control of voluntary and reflex movements. The motor system can be divided into (1) the peripheral apparatus, which consists of the anterior horn cell and its peripheral axon, the neuromuscular junction, and muscle, and (2) the more complex central
apparatus, which includes the descending tracts involved in control (i.e., the pyramidal system) and the systems involved in initiating and regulating movement (the basal ganglia and cerebellum).

Dysfunction in individual components of the motor system results in fairly specific abnormalities that can be evaluated at the bedside. Although multiple components may be involved (particularly with diseases of the central nervous system) isolated involvement of the various components commonly occurs. We will consider these components in order to help you establish an orderly approach to motor system evaluation.
