An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a highly specialized surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause and manner of death or to evaluate any disease or injury that may be present for research or educational purposes.

Lamina terminalis

The median portion of the wall of the forebrain consists of a thin lamina, the lamina terminalis, which stretches from the Interventricular foramen (Foramen of Monro) to the recess at the base of the optic stalk and contains the vascular organ of the lamina terminalis, which regulates the osmotic concentration of the blood.

Mammals are the vertebrates within the class Mammalia (from Latin mamma "breast"), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones, and mammary glands.
