tuber cinereum

The tuber cinereum is part of the hypothalamus.

The infundibulum, a hollow conical process, projects from the tuber cinereum.

Not to be confused with the tuber cinereum, nor the ala cinerea (vagal trigone).

"Müller's trigone": Part of tuber cinereum folding over the optic chiasm of the brain.

The tuber cinereum is a hollow eminence of gray matter situated between the mammillary bodies and the optic chiasm.

By its release of histamine, the tuberomamillary nucleus of the tuber cinereum helps to regulate the circadian cycle.

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

A small swelling on the tuber cinereum posterior to the infundibulum - atop the pituitary stalk - the median eminence lies in the area roughly bounded on its posterolateral region by the cerebral peduncles, and on its anterolateral region by the optic chiasm.

Tuber cinereum hamartoma (also known as hypothalamic hamartoma) is a nonneoplastic tumor in which a disorganized collection of neurons and glia accumulate at the tuber cinereum of the hypothalamus on the floor of the third ventricle.
