Muscle that lifts the upper lip and wing of the nose (M. Levator Labii Superioris Alaeque Nasi, Pna)

Levator labii muscle And wing of the nose (lat. musculus levator labii superioris, alaeque nasii) is a part of the facial skeleton that is responsible for raising the upper lip and wing of the nose. It is located on the inside of the upper jaw and is attached to the upper edge of the nasal septum. This muscle is one of the most important muscles of the face, as it is involved in the formation of facial expression and ensures normal breathing through the nose.

The muscle consists of two parts: large and small. A large piece of muscle called the levator labii superioris is located in the upper jaw and attaches to the skin above the upper lip. A small part of the muscle, the “ala”, is located on the side wall of the nose and is attached to the lower part of the nostril.

When the muscle contracts, it lifts the upper lip and the wing of the nose upward. This allows a person to speak more clearly and clearly, and also helps with breathing through the nose. In addition, this muscle plays an important role in the formation of a smile and the expression of emotions.

With muscle pathology, a number of problems can arise, such as drooping upper lip, difficulty breathing through the nose, facial asymmetry, etc. Treatment may include surgical correction, physical therapy, massage and other methods.

Overall, the levator labii nasi muscle is an important part of the facial skeleton and plays a key role in facial expression, breathing and other functions of the human body.
