The auricle is an irregularly shaped cartilaginous structure covered by a thin layer of skin. It is continuous with the external acoustic meatus, a tubular component of the externa l ear. The lateral one-third of the meatus is cartilaginous, while its medial two-thirds are osseous (temporal bone). The external acoustic meatus terminates with the tympanic membrane (eardrum) which is connected to the ossicles of the middle ear. Show more
