Antihelix

Antihelix (/æntiˈhiːlɪks/) is a part of the visible ear anatomy, specifically located within the pinna (or auricle). The term is derived from the Greek words 'anti' meaning 'against' and 'helix' meaning 'spiral'.

Anatomy

The antihelix is a curved prominence of cartilage that parallels and is located directly in front of the helix. It forms a 'Y' shape where the stem of the 'Y' is continuous with the fossa of the antitragus. The upper branches of the 'Y' end at the two crura of the antihelix.

Function

The antihelix helps to direct sound waves from the environment into the ear canal for processing. It also contributes to the unique shape of the human ear, which aids in the localization of sound sources.

Related Terms

  • Helix: The outer rim of the ear, located directly behind the antihelix.
  • Antitragus: A small tubercle opposite the tragus, located at the base of the antihelix.
  • Crura: The two branches or 'legs' of the antihelix.
  • Fossa: A depression or hollow, often referring to the depression in the ear between the helix and the antihelix.

Etymology

The term 'antihelix' is derived from the Greek words 'anti', meaning 'against', and 'helix', meaning 'spiral'. This is in reference to its position and shape in relation to the helix of the ear.
