The fissures comprise the choroidal and hippocampal already described, and two others, viz., the calcarine and collateral, which produce the swellings known respectively as the calcar avis and the collateral eminence in the ventricular cavity.
On its medial wall is a longitudinal eminence, the calcar avis (hippocampus minor), which is an involution of the ventricular wall produced by the calcarine fissure.
The anterior part of this fissure gives rise to the prominence of the calcar avis in the posterior cornu of the lateral ventricle.
