Corpus: Supraorbital artery

The supraorbital artery is a branch of the ophthalmic artery.

The supraorbital artery originates in the orbit near the junction of the ophthalmic artery and the optic nerve. It runs anteriorly along the medial edge of the superior rectus muscle and the levator palpebrae muscle. The artery then meets the supraorbital nerve and accompanies it as it passes through the supraorbital foramen.

After exiting the foramen, the supraorbital artery divides into a deep branch and a superficial branch. These branches anastomose with the supratrochlear artery and the frontal branch of the superficial temporal artery.

Within the orbit, the supraorbital artery supplies the superior rectus muscle and the levator palpebrae muscle. Outside the orbit, it supplies the skin, muscles, and periosteum of the forehead.
