The posterior pituitary (or neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system. Despite its name, the posterior pituitary gland is not a gland, per se; rather, it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary gland.

It (the hypophysis) develops embryonically in all vertebrates from two ectodermal evaginations that meet and unite. An infundibulum grows ventrally from the diencephalon of the brain, and Rathke's pouch extends dorsally from the roof of the developing mouth, or stomodaeum. The infundibulum remains connected to the floor of the diencephalon, which becomes the hypothalamus, and gives rise to the part of the gland known as the neurohypophysis. (...) Rathke's pouch loses its connection with the stomodaeum in most adult vertebrates and gives rise to the rest of the gland, the adenohypophysis. (...) A well-developed hypophyseal system with functional connections to the hypothalamus is unique to craniates.[well established][VHOG]
