Question

the hypophyseal portal system connects the ________ with the ________.

multiple choice

anterior pituitary; posterior pituitary

anterior pituitary; hypothalamus

posterior pituitary; hypothalamus

hypothalamus; thyroid

pituitary glands; thyroid

Explanation:

The hypophyseal portal system is a network of blood vessels that plays a crucial role in the endocrine system. It specifically connects the hypothalamus (which produces releasing and inhibiting hormones) to the anterior pituitary (which then secretes hormones based on the signals from the hypothalamus). The posterior pituitary is connected to the hypothalamus via nerve fibers (not the portal system). The thyroid is not directly connected to the hypothalamus via the hypophyseal portal system.

Answer:

anterior pituitary, hypothalamus
