Definition of tragus in English:



Anatomy Zoology
  • A prominence on the inner side of the external ear, in front of and partly closing the passage to the organs of hearing.

    • ‘Megabats have relatively simple external ears; microbats often have large and relatively complex pinnae, including an enlarged tragus or antitragus.’
    • ‘Absorption may also be facilitated by manipulating the tragus to help distribute the drops throughout the external auditory canal.’
    • ‘The crown of the skull is inflated, and they have large, well-separated ears with a small tragus.’
    • ‘A quick pull on the earlobe, a push on the tragus and a look into the canal confirmed the diagnosis of external otitis.’
    • ‘They are often united by a band of skin across the forehead, and a tragus is present (a fleshy lobe that protrudes from the ear).’


Late 17th century: from late Latin, via Latin from Greek tragos goat (with reference to the characteristic tuft of hair that is often present, likened to a goat's beard).
