Anterior ramus of the lateral sulcus

A.Prof Frank Gaillard et al.

The anterior ramus of the lateral sulcus, is located at the very anterior end of the lateral sulcus (sylvian fissure), just anterior to the ascending ramus, and passes superiorly into the inferior frontal gyrus separating the pars orbitalis form the pars triangularis of the frontal operculum. 

Terminology

The anterior ramus is also sometimes referred to as the anterior horizontal ramus, so as not to confuse it with the ascending ramus which is sometimes known as the anterior ascending ramus.
