Anatomy of the Nervous System

  1. Transverse fissure of Bichat
    = lateral extension of perimesencephalic cistern separating thalamus superiorly from parahippocampal gyrus inferiorly
  2. Choroidal fissure
    = superior lateral extension of transverse fissure extending superior to hippocampus
  3. Hippocampal fissure
    = inferior lateral extension of transverse fissure extending between hippocampus and parahippocampal gyrus
  4. Temporal horn of lateral ventricle
    = lateral margin of hippocampus; separated from transverse fissure by fimbria + choroid plexus
    ◊Does not communicate with transverse fissure

Uncus

[uncus, Latin = hook]

= medial protrusion near ventral surface of parahippocampal gyrus (= innermost gyrus) of temporal lobe

Function: part of primary olfactory area
