ACTH (Adrenocorticotropic Hormone) is not secreted by the posterior pituitary; it is secreted by the anterior pituitary. The posterior pituitary releases different hormones, primarily oxytocin and vasopressin (also known as antidiuretic hormone, ADH), which are not directly involved in stimulating the adrenal medulla. ACTH is involved in the release of hormones from the adrenal cortex, not the adrenal medulla. The hormones released by the adrenal cortex include glucocorticoids like cortisol. The secretion of ACTH is regulated by the hypothalamus through the release of corticotropin-releasing hormone (CRH). ACTH is indeed a tropic hormone because it stimulates another endocrine gland to secrete hormones.
