Hypothalamic sulcus
Sulcus hypothalamicus
- Latin eponym: Sulcus Monroi
- Eponym: Sillon of Monro; Monro's sulcus
Definition
The hypothalamic sulcus refers to a shallow sulcus that separates the thalamus (superiorly) from the hypothalamus (inferiorly). Both thalamus and hypothalamus constitute the lateral wall of the third ventricle. By separating these two structures, hypothalamic sulcus defines the upper border of the hypothalamus. It extends from the interventricular foramen (a.k.a. foramen of Monroe) anteriorly, all the way back to the cerebral aqueduct.
