And we'll discuss these in much more detail when we'll discuss the reproduction cycle of the human organism. Now, the final thing that I'd like to briefly discuss is how our body actually controls the amount of corticosteroids released by our body. So how much of these hormones are found in our bloodstream? So recall in our discussion of the hypothalamus and our anterior pituitary gland, we said that the anterior pituitary gland releases a hormone known as our adrenal corticotropic hormone or ACTH. And ACTH is itself released and stimulated by a hormone released by the hypothalamus known as the corticotropic releasing factor. So the Hypothalamus stimulates the release of corticotropic releasing factor which basically stimulates the interior pituitary gland to release ACTH.
