The posterior pituitary (also known as neurohypophysis) is a direct extension from the hypothalamus and does not synthesize any hormones, but rather releases oxytocin and ADH (vasopressin) which has traveled down the infundibulum in vesicles termed Herring bodies. The cell bodies reside into hypothalamic nuclei:
- supraoptic nucleus
- paraventricular nucleus
The infundibular stalk is also considered part of the neurohypophysis and extends from the tuber cinereum and pierces the diaphragma sellae before being surrounded by the pars tuberalis of the anterior pituitary.
