Ascending ramus of the lateral sulcus

Last revised by Deleted User on 03 Oct 2016

Ascending ramus of the lateral sulcus, is located at the anterior end of the lateral sulcus (sylvian fissure), just posterior to the anterior ramus, and passes superiorly into the inferior frontal gyrus separating the pars triangularis from the pars opercularis of the frontal operculum. 

Terminology

The ascending ramus is also sometimes confusingly referred to as the anterior ascending ramus, which should not be confused with the anterior ramus which is sometimes known as the anterior horizontal ramus.
