The prefix "pinn-" is related to which part of the ear?

The prefix "pinn-" refers to the outer ear, specifically the part known as the pinna. The pinna is the visible part of the ear that protrudes from the side of the head and is responsible for capturing sound waves and directing them into the ear canal. This structure plays a crucial role in the auditory system, helping to enhance sound localization and overall hearing ability.

In contrast, the middle ear comprises structures like the ossicles (malleus, incus, and stapes) and is involved in transmitting sound vibrations from the eardrum to the inner ear. The inner ear contains the cochlea and vestibular system, playing vital roles in hearing and balance. The auditory nerve carries signals from the inner ear to the brain for processing sound. Therefore, the prefix "pinn-" specifically highlights the anatomy and function of the outer ear, making that the correct connection.
