a small, triangular projection of cartilage located in front of the ear canal, partially covering its entrance
The tragus is a small, fleshy projection located on the external part of the ear. It is composed of cartilage and is situated in front of the ear canal. The tragus helps to funnel sound waves into the ear canal and plays a role in directing and amplifying sound. It also serves as a protective feature, helping to shield the entrance of the ear canal and preventing foreign objects from easily entering.
