The external nose is a visible component of the face, projecting over and allowing entrance into the nasal cavity. This article will discuss the anatomy of the external nose – its skeletal structure, muscles, blood supply and innervation.
Where does dorsal nasal artery come from?
The Dorsal Nasal Artery (External nasal artery), the other terminal branch of the ophthalmic, 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 which crosses the root of the nose, and anastomoses with the angular …
