Primary Motor and Somatosensory Regions

Primary Motor and Somatosensory Regions

The primary motor and the primary somatosensory regions of the cerebral cortex are organized in such a way that each location on their surface corresponds to a particular part of the body. The general arrangement is similar in the two regions. Our lips are more sensitive than is the skin on our forearm. We also have greater #motor control of our lips than we do of our forearm. Areas with greater sensitivity and motor control have a proportionally larger area of representation on the cortex than do areas with less sensitivity and motor control, such as the forearm. / Biology Of Humans: concepts, applications, and issues, Benjamin-Cummings Pub Co (2011) .
