Muscle that lifts the superior lip (M. Levator Labii superioris, Pna)

**Muscle that lifts the lower lip** The nasal muscle (lat. musculus nasalis), or the levator lower lip muscle, is a small muscular ligament of the mucous membrane of the wing of the nose. It opens the opening of the nose and lowers the upper lip, which covers the lower teeth. The nasalis muscle originates from the dorsum of the nose lateral to the superior end of the orbital surface of the maxilla, is woven medially to the pterygoid process of the sphenoid bone, and is innervated by the facial branch of the maxillary nerve (V3).

The levator labii superioris muscles are two relatively weak, thick lips.

The levator labii supreioris muscle (lat. m. Levator labii supreioris, synonymous with lat. Buccinator, PNA) - see Nasopalatine muscle. From Latin levatio - “raising”

The muscle raises the upper lip, cheek, and exposes the upper teeth. Consists of muscle bundles located in the transverse direction. The bundles pass into tendons (fascia) and are attached to the upper jaw and the lower edge of the upper lip. In the oral cavity, the muscle is closely adjacent to the periosteum of the alveolar processes of the jaws.
