Sheep Brain — Ventral View

The ventral surface of the diencephalon features three structures in rostro-caudal order: optic chiasm (green pic), infundibulum (orange), and mamillary bodies (red). The infundibulum is a hollow stalk that connects to the neurohyphysis, which is missing in this specimen. Non-diencephalic structures also labeled in this specimen are: crus cerebri (yellow), pons (white), trapezoid body (blue), and pyramid (green).
