earlobe
Fleshy extension of the lower section of the auricle; it plays no role in hearing.
acoustic meatus
Opening through which sounds collected by the auricle reach the tympanic cavity.
tragus
Flat triangular protuberance located in front of the acoustic meatus, protecting especially the concha.
anterior notch
Deep depression separating the helix from the tragus.
crus of helix
Front portion of the helix beginning at the base of the concha.
triangular fossa
Small depression located in the upper portion of the helix between its two branches.
tail of helix
Terminal end of the helix extending to the upper portion of the lobe.
antitragus
Small triangular protuberance at the terminal end of the antihelix.
intertragic notch
Deep depression at the base of the acoustic meatus between the antitragus and the tragus.
concha
Deep cavity of the auricle of the ear above the antitragus; the acoustic meatus opens into it.
antihelix
Protuberance parallel to and inside the helix dividing into two branches in its upper section.
helix
Protruding fold of the auricle of the ear extending from the concha to the lobe.
