Pituitary gland secretes hormones. All releasing hormones (-RH) referred to, can also be referred to as releasing factors (-RF). Somatotropes: Corticotropes: Thyrotropes: Gonadotropes: Lactotropes: These hormones are released from the anterior pituitary under the influence of the hypothalamus. Hypothalamic hormones are secreted to the anterior lobe by way of a special capillary system, called the hypothalamic-hypophysial portal system. There is also a non-endocrine cell population called folliculostellate cells. The intermediate lobe synthesizes and secretes the following important endocrine hormone: The posterior pituitary stores and secretes (but does not synthesize) the following important endocrine hormones: Magnocellular neurons: Hormones secreted from the pituitary gland
Pituitary apoplexy The pituitary gland consists of two parts, the anterior (front) and posterior (back) pituitary. Both parts release hormones that control numerous other organs. In pituitary apoplexy, the main initial problem is a lack of secretion of adrenocorticotropic hormone (ACTH, corticotropin), which stimulates the secretion of cortisol by the adrenal gland. This occurs in 70% of those with pituitary apoplexy. A sudden lack of cortisol in the body leads to a constellation of symptoms called "adrenal crisis" or "Addisonian crisis" (after a complication of Addison's disease, the main cause of adrenal dysfunction and low cortisol levels). The main problems are low
