The posterior pituitary gland stores and releases two hormones synthesized by the hypothalamus: oxytocin and vasopressin (antidiuretic hormone).
ADH (antidiuretic hormone) is synthesized in the hypothalamus and then transported to the posterior pituitary gland for storage and release. Oxytocin is also synthesized in the hypothalamus and released from the posterior pituitary gland.
ADH or anti-diuretic hormone and oxytocin are synthesized by posterior pituitary and not anterior pituitary gland.
Antidiauretic hormone and Oxytocin are the two hormones released by posterior Pituitary gland. A.D.H. conserve the body water by reducing amount of urine. Oxytocin increases the milk secretion and to induce delivery you put a drip of Oxytocin. It promotes uterine contractions and relaxes the cervix to hasten delivery.
