Hormones Secreted By The Posterior Pituitary Gland
Camila Farah
In total more than 200 hormones or hormone like substances have been discovered.
Hormones produced by other glands in the body. Secretory nerve cells of the hypothalamus produce oxytocin and antidiuretic hormone adh. Two hormones are produced by the hypothalamus and then stored in the posterior pituitary gland before being secreted into the bloodstream. The posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland which is part of the endocrine system the posterior pituitary is not glandular as is the anterior pituitary instead it is largely a collection of axonal projections from the hypothalamus that terminate behind the anterior pituitary and serve as a site for the secretion of neurohypophysial hormones.
The hormones secreted by the pituitary gland are vital regulators of most of the other endocrine glands. The intermediate pituitary zone produces and secretes melanocyte stimulating hormone. Anti diuretic hormone also called vasopressin which controls water balance and blood pressure. Adrenocorticotropic hormone acth thyroid stimulating hormone tsh follicle stimulating hormone fsh lutenizing hormone lh growth hormone gh prolactin.
In addition to the hormones listed in the table above five of these hormones are controlled by hormones released by the pituitary. Hormones secreted by the middle lobe of pituitary. Oxytocin most of which is released from the paraventricular nucleus in the hypothalamus. The hormones secreted by the posterior pituitary are produced in the hypothalamus and then passed down a tube between the hypothalamus and the pituitary the pituitary stalk when they are then secreted into the blood.

Hormones secreted by anterior pituitary.The anterior pituitary lobe produces six hormones that are either stimulated or inhibited by hypothalamic hormone secretion. In addition some hormones directly control the function of specific organs.
