Auricle (anatomy)
The Auricle (pronounced: /ˈɔːrɪkəl/), also known as the pinna (plural: pinnae), is a part of the human ear. It is the visible part of the ear that resides outside of the head.
Etymology
The term "auricle" is derived from the Latin word "auricula", which means "little ear". The term "pinna" is also Latin and translates to "feather" or "wing".
Anatomy
The auricle is primarily composed of cartilage, and is covered by skin. It plays a crucial role in the process of hearing by collecting sound waves and directing them into the ear canal. The unique shape of the auricle helps to enhance sound and determine the direction from which it is coming.
