Inferior hypophysial artery
The inferior hypophysial artery is an artery in the head. It is a branch of the cavernous carotid artery, itself from the internal carotid artery. It supplies the posterior pituitary of the pituitary gland.

Structure
The inferior hypophysial artery is a branch of the cavernous carotid artery, itself from the internal carotid artery.[1][2] Alternatively, it may arise from the meningohypophyseal artery.[3] It passes across the middle of the cavernous sinus. It reaches the lateral surface of the posterior pituitary.[3] It merges with the other inferior hypophysial artery.[3]
The inferior hypophysial artery may give off the medial clival artery.[3]
Function
The inferior hypophysial artery supplies the pituitary gland,[4] specifically the posterior pituitary (neurohypophysis).[5] It is important for distributing vasopressin into the bloodstream.[6]
History
The inferior hypophysial artery was first identified in 1860 by Hubert von Luschka.[3]
