Antidiuretic hormone - Normal and disordered function

In humans and most other mammals, the antidiuretic hormone (ADH) is a nonap eptide often referred to as arginine vasopressin (AVP). It is produced by l arge neurons that originate in the supraoptic and paraventricular nucleus o f the hypothalamus and project through the pituitary stalk to terminate on capillary plexuses scattered throughout the posterior pituitary. These plex uses drain into the systemic circulation by way of the cavernous sinus and superior vena cava.
