Brain: Marginal sulcus

Medial surface of left cerebral hemisphere. (Marginal sulcus not labeled, but region is visible at upper left.)
Latin	ramus marginalis; sulcus marginalis
NeuroNames	hier-80
NeuroLex ID	birnlex_4030

The marginal sulcus is the portion of the cingulate sulcus adjacent to the paracentral lobule and the precuneus. It is sometimes known as the "marginal part of the cingulate sulcus".
