compressor naris muscle

The transverse part (compressor naris) 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.

Origin :-

The muscle originates in the maxilla (upper jaw) part of the skull and inserts into the nasal bone. The nasalis muscle is comprised of two regions: the transverse and the alar. The transverse section arises from the maxilla and covers the bridge of the nose. The alar is attached to the greater alar (nostril) cartilage, which is situated between the tissue of the nostril and the lateral cartilage.

The transverse part (compressor naris) 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. It compresses the nostrils and may completely close them.

Nerve supply :-

nasalis muscle is innervated by the seventh cranial nerve: the facial nerve.
