The '''Depressor septi''' (Depressor alœ nasi) arises from the [[incisive fossa]] of the [[maxilla]].
Its fibers ascend to be inserted into the [[nasal septum]] and back part of the alar part of [[nasalis muscle]].
It lies between the [[mucous membrane]] and muscular structure of the [[lip]].
==Action==
The Depressor septi is a direct antagonist of the other muscles of the nose, drawing the [[ala of the nose]] downward, and thereby constricting the aperture of the [[nares]].
