Human ear - Anatomy, Hearing, Balance: The most-striking differences between the human ear and the ears of other mammals are in the structure of the outermost part, the auricle. In humans the auricle is an almost rudimentary, usually immobile shell that lies close to the side of the head. It consists of a thin plate of yellow elastic cartilage covered by closely adherent skin.
