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.
