Crh hormone acth
WebCorticotropin-releasing hormone (CRH) is the primary stimulator of ACTH release, but vasopressin plays a role during stress. ACTH induces the adrenal cortex to release cortisol and several weak androgens, such as dehydroepiandrosterone (DHEA). WebIn the HPA axis, the parvocellular neurosecretory cells release a hormone called corticotropin-releasing hormone (CRH) into a specialized capillary system that lies between the hypothalamus and the pituitary called the hypophyseal portal circulation.
