Which hormone may be in high concentrations in the hypophyseal portal vein?
Hypophyseal portal system is a system of blood vessels that is responsible for connection between hypothalamus and anterior pituitary. The hormones produced by the neuroendocrine cells of the hypothalamus are transported to the anterior pituitary through the hypophyseal portal vein. The hypothalamus produces releasing and inhibiting hormones and these hormones act on the anterior pituitary.
Gonadotropin releasing hormone (GnRH) is produced by the hypothalamus and is carried to the anterior pituitary through the hypophyseal portal vein. In the anterior pituitary GnRH acts on its receptors and leads to the production of Luteinizing hormone and follicle stimulating hormone, which play an important role in regulating reproductive activities.
