We have the medium eminence which is the bottom portion of the hypothalamus and this is our pituitary gland also known as the hypothesis. This is the front portion, the interior pituitary gland and the back portion, the posterior pituitary gland. Now, what exactly connects, what links the hypothalamus to the interior pituitary gland? Well, it's basically a network of blood vessels, a network of capillaries and veins and arteries that actually connects the hypothalamus to our interior pituitary. And because the pituitary gland is also known as the hypothesis, this network of blood vessels is also known as the hypothesia portal system. So basically at the top portion of our blood vessel system we have the superior hypothesial artery.
