adrenocorticotropic hormone definition
Adrenocorticotropic hormone (ACTH), also known as corticotropin (INN, BAN) (brand names Acortan, ACTH, Acthar, Acton, Cortigel, Trofocortina), is a polypeptide tropic hormone produced and secreted by the anterior pituitary gland.onversely, deficiency of ACTH is a cause of secondary adrenal insufficiency, often as a result of hypopituitarism. ACTH is also related to the circadian rhythm in many organisms. In addition to its endogenous role, ACTH is used clinically as a diagnostic agent in assessing adrenal function. ACTH. n. Adrenocorticotropic hormone; a hormone that is produced by the anterior lobe of the pituitary gland and that stimulates the secretion of cortisone, aldosterone, and other hormones by the adrenal cortex.Also called adrenocorticotropin, adrenotropin, corticotropin.CTH. adrenocorticotropic hormone; produced by the anterior lobe of the pituitary gland that stimulates the cortex of the adrenal gland to secrete its hormones, including corticosterone. If production of ACTH falls below normal, the adrenal cortex decreases in size, and production of the cortical hormones declines.

Called also corticotropin.1  Facebook.drenocorticotropic hormone (ACTH), a hormone of the adenohypophysis that stimulates growth of the adrenal cortex and the synthesis and secretion of corticosteroids. Adrenocorticotropic hormone, as its name implies, stimulates the adrenal cortex. More specifically, it stimulates secretion of glucocorticoids such as cortisol, and has little control over secretion of aldosterone, the other major steroid hormone from the adrenal cortex.drenocorticotropic hormone, as its name implies, stimulates the adrenal cortex. More specifically, it stimulates secretion of glucocorticoids such as cortisol, and has little control over secretion of aldosterone, the other major steroid hormone from the adrenal cortex. It is an important component of the hypothalamic-pituitary-adrenal axis and is often produced in response to biological stress (along with its precursor corticotropin-releasing hormone from the hypothalamus). Its principal effects are increased production and release of cortisol by the cortex of the adrenal gland.onversely, deficiency of ACTH is a cause of secondary adrenal insufficiency, often as a result of hypopituitarism. ACTH is also related to the circadian rhythm in many organisms. In addition to its endogenous role, ACTH is used clinically as a diagnostic agent in assessing adrenal function.
