WebAdrenocorticotropic hormone (corticotropin; ACTH) is a 39 amino acid peptide hormone produced by cells of the anterior pituitary gland and carried by the peripheral circulation to its effector organ, the adrenal cortex, where it stimulates the synthesis and secretion of glucocorticoids and, to a more modest extent, mineralocorticoids and adrenal … WebJun 11, 2016 · The corticotrophs ( ACTH-producing cells) and the thyrotrophs ( TSH-producing cells) are located predominantly in the anteromedial region, making them more resilient to traumatic injury. The lactotrophs (prolactin-producing cells) are dispersed throughout the pituitary, and this too is a resilient cell population.
