Английская Википедия:Interpeduncular fossa
Шаблон:Infobox brain The interpeduncular fossa is a deep depression[1] of the ventral surface of the midbrain[2]Шаблон:Rp between the two crura cerebri.[2]Шаблон:Rp[3]
It has been found in humans and macaques, but not in rats or mice, showing that this is a relatively new evolutionary region.[4]
Anatomy
The interpeduncular fossa is a somewhat rhomboid-shaped area of the base of the brain.[5]
Features
The lateral wall of the interpeduncular fossa bears a groove - the oculomotor sulcus - from which[6] rootlets of the oculomotor nerve emerge from the substance of the brainstem[6][2]Шаблон:Rp and aggregate into a single fascicle.[2]Шаблон:Rp
Anatomical relations
The ventral tegmental area lies at the depth of the interpeduncular fossa.[2]Шаблон:Rp
Boundaries
The interpeduncular fossa is 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.[5]
The floor of interpeduncular fossa, from behind forward,Шаблон:Citation needed are the posterior perforated substance,[1] corpora mamillaria, tuber cinereum, infundibulum, and pituitary gland.Шаблон:Citation needed
Contents
Contents of interpeduncular fossa include oculomotor nerve, and circle of Willis.Шаблон:Citation needed
The basal veins pass alongside the interpeduncular fossa before joining the great cerebral vein.[2]Шаблон:Rp
Clinical significance
The most common locations for neurocutaneous melanosis have occurred along the interpeduncular fossa, ventral brainstem, upper cervical cord, and ventral lumbosacral cord.[7]
