Depressor septi nasi muscle
Template:Muscle infobox 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.
Works like the alar part of the nasalis muscle.
