From Wikipedia, the free encyclopedia
On the anterior surface of the maxilla, just above the eminences corresponding to the incisor teeth is a depression, the incisive fossa, which gives origin to the Depressor alæ nasi; to the alveolar border below the fossa is attached a slip of the Orbicularis oris; above and a little lateral to it, the Nasalis arises.
