Pronunciation: [ˈanθɪlˌɪks] (IPA) 
The word "Anthelix" is a term used in anatomy to describe the inner part of the outer ear. As for its spelling, it can be broken down into two syllables: "ant" and "helix". The stress is on the second syllable, and the "a" in "ant" is pronounced as in "cat". The "h" in "helix" is silent, and the "e" and "i" are pronounced as a short "e" and a long "i", respectively. Therefore, the IPA transcription for "anthelix" is /æntˈhi.lɪks/.
The anthelix is a prominent, curved part of the external ear that lies adjacent to and parallel with the concha. It is composed of cartilage and forms an essential structural element of the ear's framework. The anthelix is located on the superior aspect of the helix, constituting the inner side of the outer ear, and extends from the base to the apex of the pinna.
Characterized by its intricate folding pattern, the anthelix is comprised of two ridges of cartilage that begin at the antitragus and descend across the pinna towards the earlobe. The arrangement and shape of the anthelix may vary from individual to individual, resulting in unique ear shapes.
The primary function of the anthelix is to support and maintain the structural stability of the ear. It aids in capturing and funneling sound waves towards the ear canal, where they are then transmitted to the middle and inner ear for further processing and interpretation.
The anthelix also contributes to the aesthetic appearance of the ear, adding depth and contour to its overall shape. Its curvature may influence the angle and inclination of the ear, giving each person their distinct ear morphology.
Overall, the anthelix plays a crucial role in the anatomical and functional aspects of the external ear, serving as an integral component in sound reception and ear morphology.
An elevated ridge of cartilage anterior and roughly parallel to the posterior portion of the helix of the auricle.

The word "Anthelix" originates from the combination of two Greek words: "anti" meaning "opposite" or "counter", and "helix" meaning "spiral" or "coil". The helix refers to the curved outer rim of the ear, while the prefix 'anti-' emphasizes the opposite or mirror image nature of the anatomical structure. Hence, "Anthelix" represents the distinctive feature of the pinna or outer ear's curving ridge facing the direction opposite to the helix.
