Tragus
Tragus
The Tragus (/ˈtreɪɡəs/; plural: traguses or tragi) 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 flap of cartilage that lies immediately in front of the ear canal.
Etymology
The term "tragus" is derived from the Greek word "tragos", which means goat. This could be due to the tuft of hair that grows on the tragus, resembling a goat's beard.
Anatomy
The tragus is a prominent part of the external ear and plays a role in directing sounds into the ear for processing. It is composed of a thin layer of skin over a core of cartilaginous tissue. It is located just in front of the auricle (the visible part of the ear) and the opening to the ear canal.
Related Terms
- Anti-Tragus: The cartilaginous prominence that is parallel and slightly superior to the tragus.
- Concha: The deepest indentation of the external ear, leading directly to the ear canal.
- Auricle: The visible part of the ear that resides outside of the head.
- Ear Canal: The tube-like structure that extends from the outer ear to the eardrum.
Piercing
The tragus is a popular location for ear piercings, known as Tragus Piercing. This type of piercing requires a needle to pass through the cartilaginous tissue, which can be more painful and take longer to heal than piercings in the earlobe.
