Alveus of the hippocampus

Brain: Alveus of the hippocampus

Inferior and posterior cornua, viewed from above. (Alveus not labeled, but "fimbria hippocampus" is identified at center right.)
Latin	alveus hippocampi
NeuroNames	hier-168
Dorlands/Elsevier	a_27/12123782

The alveus of the hippocampus borders the wall of the lateral ventricle and is composed of white, myelinated fibers. The alveus arises from cell bodies in the subiculum and hippocampus, and eventually merges with the fimbria of the hippocampus. The fimbria goes on to become the fornix. These structures are part of the limbic system.
