Which structures comprise the outer ear?

The outer ear is made up of the pinna (the visible part of the ear) and the external auditory canal. These structures are responsible for collecting sound waves from the environment and guiding them into the ear toward the eardrum. The pinna helps with sound localization, and the ear canal channels and a bit of resonance aids to boost certain frequencies. The ossicles belong to the middle ear, where they transmit and amplify vibrations from the eardrum to the inner ear. The cochlea and semicircular canals are in the inner ear, with the cochlea translating vibrations into neural signals for hearing and the semicircular canals involved in balance. So, the pinna plus the auditory canal correctly identify the outer ear.
