Also known as vasopressin, ADH is a neuropeptide hormone (small protein produced by nerve cells) that is synthesised in the hypothalamus. Once produced, ADH is transported along the axons of hypothalamic neurones to be stored in the posterior pituitary gland. There are several potential triggers that stimulate the release of ADH, including a decrease in BP as detected by the aortic arch and carotid sinus baroreceptors, an increase in blood concentration as detected by hypothalamic osmoreceptors (receptors that measure the osmotic potential of the blood) and the presence of angiotensin-II from the rennin angiotensin aldosterone mechanism (see section on RAAS below).
