depressor septi |
Also found in: Wikipedia | 0.02 sec. |
|
depressor septi [sep′tī] one of the three muscles of the nose. Arising from the maxilla and inserting into the septum and the posterior aspect of the ala, it lies between the mucous membrane and the muscular structure of the lip and is a direct antagonist of the other muscles of the nose. It is innervated by buccal branches of the facial nerve and serves to draw down the ala, constricting the nostril. Compare nasalis, procerus. How to thank TFD for its existence?
