c. Hypothalamus
d. Pineal
ANS: B
The posterior pituitary secretes ADH, which is also called vasopressin, and oxytocin. The anterior pituitary secretes ACTH, melanocyte-stimulating hormone (MSH), somatotropic hormones (GH, prolactin), and glycoprotein hormones—follicle-stimulating hormone (FSH), LH, and TSH. The hypothalamus secretes PRF, which stimulates secretion of prolactin; PIF (dopamine), which in-hibits prolactin secretion; TRH, which affects release of thyroid hormones; GH-releasing hor-mone (GHRH), which stimulates the release of GH; somatostatin, which inhibits the release of GH; gonadotropin-releasing hormone (GnRH), which facilitates the release of FSH and LH; cor-ticotropin-releasing hormone (CRH), which facilitates the release of ACTH and endorphins; and substance P, which inhibits ACTH release and stimulates release of a variety of other hormones.
The pineal gland secretes melatonin.
