So the antiduretic hormone also known as vasopressin. And we'll see why it's given this name in just a moment. This hormone is produced in the cell bodies, in the rough endoplasmaticulum of the cell bodies of the supraoptic nuclei. 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.
