And both of these proteins are small polypeptides and that means they are both synthesized in the rough endoplasmic reticulum of the cell nuclei, in the cell bodies of these nuclei, in the hypothalamus. So let's discuss how they are actually produced and what their functionality is and when they are released. And let's begin with the antidiauretic hormone also known as ADH. 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.
