It also increases certain cells, it increases the rate at which they undergo mitosis. So our human growth hormone builds up the supply of glucose so that cells can use that glucose to grow. It also causes the non growing cells to increase the use of fatty acids and increases the size as well as the number of cells in our body. And it's controlled by the GHRH hormone released by the hypothalamus. Now, let's move on to the second type of hormone that is released by the interior pituitary gland known as our adrenal corticotropic hormone or ACTH. Now, the hormone that is released by the hypothalamus that stimulates the release of ACTH from the anterior pituitary gland is known as the corticotropin releasing factor or CTF.
