Rhinal fissure

From Wikipedia, the free encyclopedia

Brain: Rhinal fissure
Latin	fissura rhinalis
Gray's	subject #184 744
NeuroNames	hier-22

The rhinencephalon appears as a longitudinal elevation, with a corresponding internal furrow, on the under surface of the hemisphere close to the lamina terminalis; it is separated from the lateral surface of the hemisphere by a furrow, the external rhinal fissure (or rhinal sulcus), and is continuous behind with that part of the hemisphere, which will ultimately form the anterior end of the temporal lobe.
