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

tructure

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
*tuberomamillary nucleus [ [http://patients.uptodate.com/abstract.asp?TR=pituitar/4659&viewAbs=5~6&title=5,6 patients.uptodate.com - Abstracts for References 5 and 6 of 'Hypothalamic-pituitary axis'] ]
