The tragus is a small, rounded prominence located at the front of the outer ear, specifically at the entrance of the ear canal. It plays a role in directing sound waves into the ear and helps protect the ear canal from debris and water. The tragus is made of cartilage and is covered by skin, making it a flexible part of the ear. In addition to its anatomical function, the tragus is often a site for body piercings. Many people choose to get a tragus piercing for aesthetic reasons, as it can be adorned with various types of jewelry. This has made the tragus a popular area for self-expression in body art.
