Which term describes the small eminence opposite the tragus?

The antitragus is the small eminence located opposite the tragus, which is a prominent structure on the outer ear. This anatomical feature is part of the external ear and plays a role in the overall shape and function of the auricle. The tragus and antitragus are both involved in directing sound waves into the ear canal, enhancing the ability to hear sounds coming from different directions.

Understanding the positioning of the antitragus in relation to the tragus helps in the identification of ear anatomy, which can be important in various audiological assessments and when fitting hearing instruments. Other terms like helix, concha, and lobule describe different parts of the ear and do not refer to the eminence opposite the tragus. The helix refers to the outer rim of the ear, the concha is the bowl-shaped part of the outer ear leading into the ear canal, and the lobule is the fleshy lower part of the ear. Thus, identifying the antitragus is crucial for understanding ear structure and function.
