The '''nasalis''' ('''compressor naris''') is a [[sphincter]]-like muscle of the nose whose function is to compress the [[nasal cartilage]].
It consists of two parts, ''transverse'' and ''alar'':
* The ''transverse part'' arises from the [[maxilla]], above and lateral to the [[incisive fossa]]; its fibers proceed upward and medially, expanding into a thin [[aponeurosis]] which is continuous on the bridge of the nose with that of the muscle of the opposite side, and with the aponeurosis of the [[Procerus]].
* The ''alar part'' is attached at one end to the [[greater alar cartilage]], and at the other to the integument at the point of the nose.
Other sources divide it into "Compressor nasalis" and "[[dilatator naris muscle|Dilator nasalis]]".<ref>{{GPnotebook|-1945763781}}</ref>
