In medical terms, "pinn-" refers to which section?

"Pinn-" is a prefix derived from the Latin word "pinna," which means "wing" or "fin" but in medical terminology specifically refers to the outer ear. The outer ear includes the visible part of the ear, known as the pinna or auricle, which helps to collect sound waves and direct them into the ear canal. This anatomical designation distinguishes the outer ear from the other sections of the ear, such as the middle and inner ear, which have different functions and structures. Understanding this terminology is essential for accurately interpreting and communicating about ear anatomy and associated medical conditions.
