And once we produce them, we package them into special secretary vesicles and they travel through the axon all the way to the posterior pituitary gland. And once they arrive in the posterior pituitary gland, we store them in specialist secretary vesicles known as the herring bodies. And we store them until they are released, until a certain type of stimulation takes place. The question is what stimulates the release of our ADH of the vasopressin? So the vasopressin, our antidiaretic hormone, is basically stimulated by the following. When we basically have an increase in the osmolarity of our blood, meaning the blood volume decreases, the amount of fluid, the amount of water in the blood decreases at the same time the amount of solute increases.
