Homonym: Auricle (Ear)
The auricle, also known as the pinna, is the visible part of the outer ear. It is made of cartilage and skin, and its primary function is to collect sound waves and direct them into the ear canal. The unique shape of the auricle helps in locating the direction of sounds, enhancing our ability to hear.
In addition to its role in hearing, the auricle also plays a part in protecting the inner structures of the ear. It helps to prevent debris and foreign objects from entering the ear canal, contributing to overall ear health.
