Etymology

The word 'pinna' originates from Latin, meaning 'feather' or 'wing'. The term was used in classical texts to describe various anatomical structures that resemble the shape of a feather or wing, particularly in reference to parts of the ear. Its application in modern biology stems from this historical association, where it is utilized to describe the protruding parts of external body structures. As the scientific understanding of anatomy and marine life evolved, 'pinna' became a formal term in both human anatomy and marine biology, reflecting the structuresโ€™ functional significance in sound collection and environmental adaptation.
