Anatomical terms of neuroanatomy

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

Structure[edit]

Laterally it is continuous with the anterior perforated substances and anteriorly with a thin lamina, the lamina terminalis.

The infundibulum, a hollow conical process, projects from the tuber cinereum. The infundibulum extends forward and down where it is attached to the posterior lobe of the pituitary gland.

It houses the nuclei:

  • tuberal nucleus
  • tuberomammillary nucleus[1]

Tuberomammillary nucleus[edit]

The tuberomammillary nucleus (TMN) is the sole source of histamine in the brain.[2]

Function[edit]

Circadian rhythm[edit]

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