Which Hormone Stimulates the Thirst Mechanism

Question

Which hormone stimulates the thirst mechanism?
A)ADH
B)epinephrine
C)aldosterone
D)natriuretic peptides
E)norepinephrine

Accepted Answer

ADH, or antidiuretic hormone, is released from the posterior pituitary gland when osmoreceptors in the hypothalamus detect high concentrations of solutes in the bloodstream. ADH acts on the kidneys to promote water retention and concentrate urine, and it also stimulates the thirst mechanism to encourage water intake.
