| Description | The motor cortex generates and controls motor commands, which are transmitted to the descending pyramidal and extrapyramidal tracts. The cerebral cortex consists of three reciprocally interconnected areas: primary motor cortex, supplementary motor cortex and premotor cortex (Figure 9.1). The primary motor cortex (Brodmann's area 4), located in the precentral sulcus, has a topographical representation of the body (motor homunculus) with the head, face and hands represented laterally and the legs and feet medially. The more complex the movement of a particular part of the body, the more motor cortex is devoted to it. The tongue, lips and hands have a much greater representation because of the complexity of their motor activity. The primary motor cortex is responsible for the control of voluntary movements.
