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]

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]

The inferior hypophysial artery was first identified in 1860 by Hubert von Luschka.^[3]
