GENERAL HISTOLOGY

Detailed explanation-1: -The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain.

Detailed explanation-2: -The primary motor cortex is located in the precentral gyrus; the premotor area is more rostral.

Detailed explanation-3: -Primary Motor Cortex Functions In a normal functioning primary motor cortex, signals cross over the center of the body to activate muscles on the opposite side. This means that the movements on the right side of your body are controlled by the left hemisphere of the primary motor cortex, and vice versa.
