Equine Brain — Median View

Medial view of an equine half brain. Components of the diencephalon are labeled. The interthalamic adhesion (inter) is surrounded by third ventricle (III). The third ventricle communicates with each lateral ventricle through an interventricular foramen. The floor of the hypothalamus features the optic chiasm (II), the infundibulum, to which the hypophysis (H) is attached, and a mamillary body (m). (Note: the terms "hypophysis" and "pituitary gland" are synonymous.) The equine pineal body is prominent and often pigmented, as is the case here. For a lateral view of the diencephalon, click here.

The rostral colliculus (mid) of the midbrain is labeled.
