The auricula is based on a complex form of elastic cartilage (cartilago auriculae), covered with a densely attached skin to the cartilage. There is no cartilage in the lower part of the auricle. Instead, there is a skin fold with a fat tissue inside - a lobulus auriculae - a lobe. The free edge of the shell is wrapped, forms a curl (helix), which ends in the anterior part of the shell over the external ear canal in the form of a crus helicis. On the inside of the curl, in the posterior-upper part of it, there is not always a clearly pronounced projection - the tubercle of the ear (tuberculum auriculae; Darwin's tubercle). In parallel, the curl on the inside of the shell is elevated - antifirets (antihelix). In front of the ear canal there is a protrusion - a tragus (tragus). Opposite him, at the bottom of the antiflora, you see an antitragus (antitragus). Between the peduncle in front and the lower part of the counter-defense from the rear is a cavity (cavitas conchae), which extends into the external auditory canal. The size and shape of the auricle are individual.
