lateral orbital sulcus
Acronym: los
The term lateral orbital sulcus refers to a superficial feature identified by dissection on the ventral surface of the frontal lobe. In the human it constitutes the lateral leg of the H-shaped orbital sulci. It separates the lateral orbital gyrus from the (more medial) posterior orbital gyrus, which lies caudal to the transverse orbital sulcus. Rostral to the transverse orbital sulcus, it separates the lateral orbital gyrus from the (more lateral) orbital part of the inferior frontal gyrus ( Mai-1997 ). In the macaque it separates the lateral orbital gyrus from the fronto-orbital gyrus ( Martin-2000 ).
     Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
