Oxytocin is a hormone that plays a crucial role in lactation by causing the let-down reflex that releases milk from the breasts. It is produced in the hypothalamus and then stored and released from the posterior pituitary gland. This is why the correct answer is that oxytocin is released from the posterior pituitary gland. Options A, B, and C are incorrect because oxytocin is not released from the adrenal glands, the thyroid gland, or the anterior pituitary gland.
