GENERAL HISTOLOGY

Detailed explanation-1: -The precentral gyrus is a diagonally oriented cerebral convolution situated in the posterior portion of the frontal lobe. It is located immediately anterior to the central sulcus (fissure of Rolando), running parallel to it 1-2.

Detailed explanation-2: -Excerpt. The precentral gyrus is on the lateral surface of each frontal lobe, anterior to the central sulcus. It runs parallel to the central sulcus and extends to the precentral sulcus. The primary motor cortex is located within the precentral gyrus and is responsible for the control of voluntary motor movement.

Detailed explanation-3: -The postcentral gyrus is immediately posterior to the central sulcus, behind and parallel to the motor strip. It corresponds to the primary somatosensory cortex (BA 3, 1 and 2).

Detailed explanation-4: -Precentral gyrus controls voluntary motor movements while postcentral gyrus controls involuntary functions. Precentral gyrus is found on the lateral surface of the frontal lobe and anterior to the central sulcus, while postcentral gyrus is situated in the lateral parietal lobe of the brain.
