Levator labii superioris

From WikiMD.com - Food, Medicine & Wellness Encyclopedia

Levator labii superioris is a muscle in the human face that elevates the upper lip, aiding in facial expressions like surprise or disgust. It is one of the muscles involved in the facial expression system, and is controlled by the facial nerve.

Anatomy[edit | edit source]

The levator labii superioris originates from the infraorbital margin of the maxilla, just below the infraorbital foramen. It inserts into the skin of the upper lip, blending with the muscles of the area. It is a broad, flat muscle, and is sometimes divided into two parts: a medial part, which is also known as the levator labii superioris alaeque nasi, and a lateral part.

Function[edit | edit source]

The primary function of the levator labii superioris is to elevate the upper lip, which contributes to facial expressions such as surprise, disgust, and sadness. It also assists in deepening the nasolabial furrow during these expressions. In addition to these functions, the muscle also helps in the process of eating and speaking.

Clinical significance[edit | edit source]

Damage to the levator labii superioris can result in a decreased ability to move the upper lip, which can affect facial expressions, speech, and eating. This can occur due to trauma, surgery, or neurological conditions that affect the facial nerve. Treatment typically involves physical therapy to restore function, and in some cases, surgery may be required.
