Superior hypophyseal artery

The superior hypophyseal artery (Latin: arteria hypohysialis superior) is a branch of the internal carotid artery. It supplies several parts of the pituitary gland.

The superior hypophyseal artery arises near the cavernous sinus. It then passes upwards to the medial eminence, and forms a primary plexus that provides the hypothalamic-portal circulation.

Regions supplied by the superior hypophyseal artery include the pars tuberalis and infundibulum of the pituitary gland, the medial eminence of the floor of the fourth ventricle, as well as the optic nerve (CN II) and optic chiasm.
