Antitragus
Antitragus
Antitragus (pronunciation: an-ti-tray-gus) is a prominent anatomical feature of the human ear. It is a small tubercle or eminence located directly opposite the tragus.
Etymology
The term 'antitragus' is derived from the Greek words 'anti', meaning 'against', and 'tragos', meaning 'goat'. This is likely due to the antitragus' position opposite the tragus, which is named for its hairiness, reminiscent of a goat's beard.
Anatomy
The antitragus is part of the auricle or outer ear. It is located above the lobe and faces the tragus across the intertragic notch. The antitragus is composed of cartilage covered by skin and is typically smaller than the tragus. It plays a role in collecting and directing sound waves into the external auditory canal.
