=====Interpeduncular fossa=====
{{ ::interpeduncular_fossa.gif|}}The interpeduncular fossa is a somewhat rhomboid-shaped area of the base of the brain, limited in front by the [[optic chiasma]], behind by the antero-superior surface of the [[pons]], antero-laterally by the converging [[optic tract]]s, and postero-laterally by the diverging [[cerebral peduncle]]s.

The structures contained in it, from behind forward, are the posterior perforated substance, corpora mamillaria, [[tuber cinereum]], infundibulum, and [[pituitary gland]].

The [[subtemporal approach]] is one of the surgical routes used to reach the [[interpeduncular fossa]].
