WebNov 23, 2024 · 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 … The precentral gyrus lies in front of the postcentral gyrus - mostly on the lateral (convex) side of each cerebral hemisphere - from which it is separated by the central sulcus. Its anterior border is represented by the precentral sulcus, while inferiorly it borders to the lateral sulcus (Sylvian fissure). Medially, … See more The precentral gyrus is a prominent gyrus on the surface of the posterior frontal lobe of the brain.
