optic chiasm (green pic) marks the rostral end of the hypothalamus (
optic nerves are rostral and
optic tracts are caudal to the chiasm).
Mamillary bodies (red) mark the caudal end of the hypothalamus. Between these, the orange pic is in the lumen of the pituitary stalk (infundibulum). To return to the dorsal view, click
