The pituitary gland, also known as the hypophysis, is a small pea-sized lump of tissue connected to the inferior portion of the hypothalamus of the brain. The last two hormones-oxytocin and antidiuretic hormone-are produced by the hypothalamus and transported to the posterior pituitary, where they are stored and later released. ![]() GnRH stimulates the release of follicle stimulating hormone and luteinizing hormone while CRH stimulates the release of adrenocorticotropic hormone. GHRH and GHIH work to regulate the release of growth hormone-GHRH stimulates growth hormone release, GHIH inhibits its release. TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone. Growth hormone-inhibiting hormone (GHIH)Īll of the releasing and inhibiting hormones affect the function of the anterior pituitary gland. ![]() Growth hormone-releasing hormone (GHRH).The hypothalamus contains special cells called neurosecretory cells-neurons that secrete hormones: It serves many different functions in the nervous system, and is also responsible for the direct control of the endocrine system through the pituitary gland. The hypothalamus is a part of the brain located superior and anterior to the brain stem and inferior to the thalamus. Anatomy of the Endocrine System Hypothalamus
