The pinna is the outermost visible part of the ear, so patrons will encounter it first. Next, they will move towards the tympanic membrane (eardrum), which is located in the middle ear. After that, they will encounter the middle ear, which contains the three small bones (ossicles) that help amplify sound vibrations. From there, they will make their way to the cochlea, the snail-shaped organ responsible for converting sound waves into electrical signals that the brain can interpret. Finally, they will reach the auditory nerve, which carries those signals to the brain for processing. Therefore, the correct order is pinna, tympanic membrane, middle ear, cochlea, and auditory nerve – which corresponds to answer choice D.
