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