The Interpeduncular fossa
is a somewhat lozenge-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 tracts, and postero-laterally by the diverging cerebral peduncles.
The structures contained in it, from behind forward, are the posterior perforated substance, corpora mamillaria, tuber cinereum, infundibulum, and hypophysis.
