Hypophyseal portal system
Hypophyseal Portal System is a system of blood vessels in the brain that connects the hypothalamus with the anterior pituitary. Its main function is to quickly transport and exchange hormones between the hypothalamus arcuate nucleus and the anterior pituitary.
Structure[edit | edit source]
The hypophyseal portal system is part of the circulatory system and is composed of two capillary beds connected by portal veins. The superior hypophyseal arteries supply blood to this system. These arteries form a primary capillary plexus in the median eminence of the hypothalamus, from which portal veins descend into the stalk of the pituitary and form a secondary capillary plexus in the anterior pituitary.
Function[edit | edit source]
The main function of the hypophyseal portal system is to transport and exchange hormones between the hypothalamus and the anterior pituitary. This system allows for the quick transport of hormones from the hypothalamus to the anterior pituitary, which is crucial for the rapid response to changes in physiological conditions.
Clinical Significance[edit | edit source]
Disorders of the hypophyseal portal system can lead to a variety of medical conditions. For example, a disruption in the transport of hormones can lead to endocrine disorders such as Cushing's disease or hypopituitarism.
