Frontomarginal Sulcus

The Fronto-Marginal Sulcus (F-MS) is a short sulcus best seen when looking at the hemisphere from its polar view. It runs horizontally from the interhemispheric fissure (1) to the lateral surface of the hemisphere, to end closely to the anterior end of the Lateral Orbital Sulcus (2). It sits at the anterior end of the Superior Frontal Sulcus (SFS).
