<prompt> Vasopressin is secreted bySupraopticPreopticParaventricularPosterior nucleus  <response>: Supraoptic nucleus nucleus supraopticus one just above the lateral pa of the optic chiasm; many of its cells are neurosecretory in function and project to the neurohypophysis, where they secrete antidiuretic hormone ADH and, to a lesser extent, oxytocin; other cells are osmoreceptors that stimulate ADH release in response to increased osmotic pressure.Ref: Ganong;s review of medical physiology; 24th edition;
