Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland, a small gland located at the base of the brain. The pituitary gland releases ACTH in response to signals from the hypothalamus. ACTH then stimulates the adrenal glands, situated atop the kidneys, to produce cortisol. Cortisol is a vital glucocorticoid hormone involved in metabolism, immune function, and the body's stress response. The regulation of ACTH and cortisol forms a crucial part of the hypothalamic-pituitary-adrenal (HPA) axis, maintaining hormonal balance.
