Inferior Hypophysial Artery

The inferior hypophysial artery is a blood vessel which arises from the internal carotid artery and supplies the pituitary gland with oxygenated blood. It divides into a medial and a lateral branch. These branches anastomose with the corresponding vessels of the opposite side, forming an arterial ring around the posterior neural lobe of the pituitary gland.
