corticotropin
Definition
Noun: * A hormone produced by the anterior pituitary gland that stimulates the adrenal cortex: Corticotropin is a peptide hormone that signals the adrenal glands (specifically the outer layer, the adrenal cortex) to produce and release its own hormones, particularly cortisol. It is a crucial part of the body's stress response system.
