Answer #1

The hypothalamus communicates with the anterior pituitary via hormones released into a special portal system of blood capillaries.

The functional connection between the hypothalamus and the anterior lobe of the pituitary is vascular. The network of blood vessels between the hypothalamus and the anterior pituitary is called the hypothalamic-pituitary portal system / circulation.

The superior hypophyseal artery drains through en bunch of capillaries into long portal vessels. These long portal vessels descend to the anterior lobe of the pituitary (adenohypophysis).

The function of this circulation is to deliver hormones to the anterior lobe of the pituitary. These hormones are produced by small neurons in the hypothalamus.

Gonadotropin-releasing hormone (GnRH) is synthesized in the hypothalamus and transported to the anterior pituitary. How does GnRH reach the anterior pituitary? Group of answer choices It is transported directly to the anterior pituitary by axons of the hypothalamic-hypophyseal tract. it is transported by axons to the posterior pituitary and diffuses from there into the anterior pituitary. It is released into the blood and travels through the systemic circulation before reaching the anterior pituitary. It is secreted into the hypophyseal portal...
