Antidiuretic hormone (ADH) release from the posterior pituitary is stimulated by:

Question

Quizplus · Accepted Answer

ADH release from the posterior pituitary is stimulated by high serum osmolarity sensed by osmoreceptors in the hypothalamus. When serum osmolarity increases, osmoreceptors in the hypothalamus are activated, which results in an increase in ADH release from the posterior pituitary. ADH then acts on the kidneys to increase water reabsorption, which helps to decrease serum osmolarity.
