Preferred Label : neural lobe of neurohypophysis;
Uberon definition : 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. [WP,unvetted].;
Uberon synonym : pars nervosa of hypophysis; pars nervosa pituitary gland; pars nervosa of neurohypophysis; pars posterior; pars nervosa of posterior lobe of pituitary gland; posterior lobe of neurohypophysis; posterior lobe-3; pars nervosa of pituitary;
Uberon related term : caudal lobe; medial eminence; neural component of pituitary; middle lobe; pars nervosa; lobe caudalis cerebelli;
Uberon broad term : PNHP; posterior lobe;
Uberon Homology note : 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];
