Multiple Choice

What is the primary function of the hypothalamic-hypophyseal portal system in hormone transport?

It transports hormones from the anterior pituitary to the hypothalamus.

It allows hormones from the hypothalamus to reach the anterior pituitary directly.

It carries hormones from the anterior pituitary to the general circulation.

It carries tropic hormones directly from the hypothalamus to the different endocrine glands around the body.

Verified step by step guidance

Understand the anatomical relationship: The hypothalamic-hypophyseal portal system is a network of blood vessels that connects the hypothalamus to the anterior pituitary gland.

Identify the primary function: The main role of this portal system is to transport hormones directly from the hypothalamus to the anterior pituitary gland.

Clarify the hormone transport process: The hypothalamus releases hormones into the portal system, which then travel directly to the anterior pituitary without entering the general circulation.

Differentiate from other functions: Unlike other systems, this portal system does not transport hormones from the anterior pituitary to the hypothalamus or to the general circulation.

Conclude with the correct function: The hypothalamic-hypophyseal portal system specifically allows hypothalamic hormones to reach the anterior pituitary directly, facilitating the regulation of pituitary hormone secretion.
