Question

Quizplus · Accepted Answer

The neurons of the hypothalamus project down to the posterior pituitary, where they release hormones such as oxytocin and vasopressin (also called antidiuretic hormone) into the bloodstream. This connection is sometimes referred to as the hypothalamic-hypophyseal tract. The anterior pituitary, also known as the adenohypophysis, is not directly connected to the hypothalamus by neurons, but rather receives regulatory signals from the hypothalamus via a network of blood vessels called the hypothalamic-pituitary portal system. The thyroid gland is not connected to the hypothalamus at all, but is regulated by the anterior pituitary via the secretion of thyroid-stimulating hormone.
