Normal Hypothalamic–Pituitary–Adrenal Physiology
Corticotropin-releasing hormone (CRH)2 is synthesized in the hypothalamus and carried to the anterior pituitary in portal blood (Figure 1). CRH, whose secretion is regulated by a variety of neurotransmitters,3 is the most potent regulator of corticotropin secretion. Arginine vasopressin and other hypothalamic agents also stimulate corticotropin secretion.4,5
Corticotropin is synthesized as a large precursor, pro-opiomelanocortin (POMC), which . . .
