Motor cortex

A Motor cortex is a part of the cerebral cortex associated with movement.

There is one primary motor cortex and three secondary motor cortices:

Primary motor cortex


 * Primary motor cortex
 * Function: Direct execution of movement
 * Location: Prefrontal gyrus, frontal lobe

Secondary motor cortices


 * Posterior parietal cortex
 * Function: Integration of visual and motor information
 * Location: Parietal lobe


 * Premotor cortex
 * Function: Planning and mental rehearsal of movement
 * Location: Premotor area, superior to Supplementary motor cortex


 * Supplementary motor cortex - a secondary motor cortex, integration of motor intent and function
 * Function: Planning and coordination of complex movements
 * Location: Premotor area, inferior to Premotor cortex
