Description
The Depressor Anguli Oris muscle is a facial muscle located in the lower lip and chin area that extends from the mandible to the Orbicularis Oris muscle. It is responsible for pulling the corners of the mouth downward and outwards, creating a frown-like expression. The muscle is used in a variety of facial expressions, including expressions of sadness, anger, and disapproval. It also plays a role in regulating the position and movement of the lower lip during speech and eating.

The importance of the Depressor Anguli Oris muscle lies in its role in maintaining proper facial expression and communication. By controlling the position and movement of the corners of the mouth, 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.
