Precentral Gyrus

Also known as:  Motor Cortex

The Precentral Gyrus is a component of the Cerebral Cortex of the Cerebral Hemispheres of the Cerebrum of the Brain.  It is located immediately in front of the Central Sulcus and immediately behind the Frontal Lobe of each Cerebral Cortex.

Nervous System & Musculoskeletal System

 Each Precentral Gyrus is involved in the control of (voluntary) Motor Movement on the opposite side of the body (contralateral) to the Cerebral Hemisphere in which it is located.

 The Precentral Gyrus is involved in the integration of Muscular activity and Sensations.

 The Precentral Gyrus receives Nerve Impulses relating to Speech from Broca's Area in the Frontal Lobes of the Cerebral Cortex.

 The Precentral Gyrus generates Nerve Impulses relating to the skilled muscle movements required for the formation of Speech.

Hormones

 Estrogens may improve Blood Circulation to the Precentral Gyrus.
