Detailed explanation-1: -The primary motor cortex is located in the precentral gyrus; the premotor area is more rostral. The pyramidal cells of cortical layer V (also called Betz cells) are the upper motor neurons of the primary motor cortex.

Detailed explanation-2: -The motor regions of the cerebral cortex are located predominantly in the frontal lobe, anterior to the central sulcus, and include the primary motor cortex (found in the precentral gyrus) and the premotor cortex, which initiates and regulates voluntary movement.

Detailed explanation-3: -The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language.
