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]
