Multiple Choice

What is the hypothalamic-hypophyseal portal system?

A network of blood vessels that connects the hypothalamus to the anterior pituitary gland, allowing for the transport of hormones.

A series of nerve fibers that connect the hypothalamus to the posterior pituitary gland, facilitating neural communication.

A collection of ducts that transport cerebrospinal fluid between the hypothalamus and the pituitary gland.

A group of lymphatic vessels that drain excess fluid from the hypothalamus to the pituitary gland.

Verified step by step guidance

Identify the key components involved in the hypothalamic-hypophyseal portal system: the hypothalamus and the anterior pituitary gland.

Understand the primary function of the hypothalamic-hypophyseal portal system, which is to transport hormones from the hypothalamus to the anterior pituitary gland.

Recognize that the system is composed of a network of blood vessels, specifically capillaries, that facilitate this hormone transport.

Differentiate between the anterior and posterior pituitary gland connections: the anterior pituitary is connected via the portal blood vessels, while the posterior pituitary is connected via nerve fibers.

Conclude that the hypothalamic-hypophyseal portal system is a network of blood vessels, not nerve fibers, ducts, or lymphatic vessels, emphasizing its role in hormone transport.
