The dorsal nasal artery (nasal artery) is an artery of the head. It is one of the two terminal branches of the ophthalmic artery.

Course

It emerges from the orbit above the medial palpebral ligament, and, after giving a twig to the upper part of the lacrimal sac, divides into two branches.

• One of these crosses the root of the nose, and anastomoses with the angular artery.
• The other runs along the dorsum of the nose, supplying its outer surface, and anastomoses with its fellow artery of the opposite side, and with the lateral nasal branch of the facial artery.
