Tragus

The tragus is a small pointed eminence of the external ear, situated in front of the concha, and projecting backward over the meatus.

It also is the name of hair growing at the entrance of the ear.

Its name comes the Ancient Greek tragos (τράγος), meaning 'goat', and is descriptive of its general covering on its under surface with a tuft of hair, resembling a goat's beard.

The nearby antitragus projects forwards and upwards.

Because the tragus faces rearwards, it aids in collecting sounds from behind.

These sounds are delayed more than sounds arriving from the front, assisting the brain to sense front vs. rear sound sources.

In a positive fistula test (for the presence of a fistula from cholesteatoma to the labyrinth), pressure on the tragus causes vertigo or eye deviation by inducing movement of perilymph.
