Auricle is also called "auricle". Also called the ear shell. Refers to the entire ear shell outside the external auditory canal. That is the outer ear. Made of cartilage and skin. The outer ear including the helix, antihelix, and earlobe. "Huangdi Nei Jing Su Wen·Qi Fu Lun": "The Qi from the Taiyang pulse of the hand...is one on each ear." In "Guangyun" Dan, Xu Kai said: "The outer part of the ear is also the wheel and Guo." Guo is located on both sides of the head, with the convex side facing backward and the concave side facing forward and outward. Most of the upper part of the auricle is supported by elastic cartilage and covered with skin; the lower part has no cartilage and only contains connective tissue and fat, which is the earlobe. There is an external auditory canal opening on the outside of the ear that leads to the external auditory canal on the inside. The shape of the auricle is conducive to collecting sound waves and playing a role in collecting sound; the auricle can also help determine the direction of the sound source. Auricle
