Tragus
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 from the Greek: tragos, 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 Fowler's test, the tragus can be seen to move forwards and backwards with pulsation.
Piercing[edit | edit source]
Tragus piercing is the process of making a hole in the tragus so as to insert jewelry. It is a form of body modification. The procedure is usually performed with a needle of small gauge.
