POSTERIOR PITUITARY
The posterior lobe of the pituitary is an outgrowth of the hypothalamus; it is called the neurohypophysis because it is derived from the nervous system. Thousands of axons descend into this lobe from cell bodies located in the hypothalamus. Capillary networks are found near the endings of the nerve fibers. The posterior lobe of the pituitary gland stores two hormones, antidiuretic hormone (ADH, also called vasopressin) and oxytocin. The hypothalamus manufactures and triggers the release of both these hormones. Antidiuretic hormones causes the kidneys to retain sufficient water for the body. Oxytocin causes the uterus to contract during childbirth and stimulates the release of milk during nursing.
