| Latin | sulcus precentralis | |
The precentral sulcus lies parallel to, and in front of, the central sulcus. (A sulcus is one of the prominent grooves on the surface of the human brain.)
The precentral sulcus divides the inferior, middle, and superior frontal gyri from the precentral gyrus. In the majority of brains, the precentral sulcus is divided into two parts: the inferior precentral sulcus and the superior precentral sulcus. However, the precentral sulcus may also be divided into three parts or form one continuous sulcus.
