- The levator labii angular muscle, blue in the examples, is used in various facial expressions, including expressions of contempt, anger, and fear. It also plays a role in regulating the position and movement of the upper lip and nose during speech and eating.
- The levator labii superioris muscle, purple in the examples, is involved in several facial expressions, including smiling, sneering, and lifting the upper lip in disgust. It also plays a role in regulating the position and movement of the upper lip during speech and eating.
The importance of the Levator labii muscle lies in its role in maintaining proper facial expression and communication. By controlling the position and movement of the upper lip, it can help to convey various emotions and facilitate effective communication. It also plays a role in proper oral function, particularly in helping to regulate the movement of food and drink during eating and drinking.
