So the hypothalamus basically produces a set of hormones of its own that ultimately are injected into the capillary bat system found within this region. This entire capillary vein artery system is known as our hypothesial portal system and it basically connects the hypothalamus to the anterior pituitary gland. So the hormones in the hypothalamus are released into the portal system and they control the release of these hormones in the endocrine cells of the anterior pituitary gland. Now, let's discuss the functionality and the purpose of the posterior pituitary gland. This section, this gland found in the back. So we have the hypothalamus, we have the posterior, the anterior pituitary gland.
