And this is known as vasoconstriction. So this is ADH. Now, what about oxytocin? Well, oxytocin is also produced in the cell bodies of our neurons. They're produced in the cell bodies of the parabentricular nuclei as well as the supra optic nuclei. And once we produce oxytocin they travel down the axon in these secretory vesicles and just like in this case they are stored in special vesicles on the axon of these neurons known as herring bodies.
