Two hormones produced by the posterior pituitary gland are __________.

Two hormones produced by the posterior pituitary gland are __________.

• A. Growth hormone (GH) and adrenocorticotropic hormone (ACTH).
• B. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
• C. Antidiuretic hormone (ADH) and oxytocin
• D. Thyroid-stimulating hormone (TSH) and growth hormone (GH)

Answer: (C)

Two hormones released by the posterior pituitary are ADH (antidiuretic hormone) and oxytocin. They aren’t made in the posterior pituitary itself; instead, they’re synthesized in the hypothalamus and travel down nerve fibers to be stored in the posterior pituitary, where they’re released in response to neural signals. ADH acts on the kidneys to increase water reabsorption in the collecting ducts, which helps regulate body water balance and blood osmolarity. Oxytocin triggers uterine contractions during labor and promotes milk ejection during breastfeeding. The other hormones listed come from the anterior pituitary, which produces different hormones like GH, ACTH, FSH, LH, and TSH.
