What does the lateral aspect of the nose supply?

This branch of the facial artery ascends along the lateral aspect of the nose. It supplies numerous structures, including the dorsum of the nose, the ala, and anastomoses with its contralateral fellow, the infraorbital branch of the internal maxillary artery as well as the dorsal nasal branch of the ophthalmic artery.

What artery forms anastomoses with the nasal artery?

The lateral nasal artery forms anastomoses with the septal branches of the superior labial artery, the angular artery, the ophthalmic artery, the internal maxillary artery, and some of the smaller arteries on the surface of the nose.
