The vestibulocochlear nerve, or 8th cranial nerve.
The ear needs the ear canal to send everything that it hears to the brain.
Sound waves travel through the ear canal and cause the eardrum to vibrate. These vibrations are passed to the cochlea in the inner ear, where hair cells are stimulated and send signals to the auditory nerve. The auditory nerve then carries these signals to the brain, which processes and interprets the sound.
The 8th cranial nerve sends messages to the brain from the ear. There are several parts involved: In the inner ear are receptor cells that receive vibrations of sound and noise from the outside, which then stimulate the cochlear nerve to send these sounds to the brain for interpretation.Head movements also affect the fluid inside the ear and stimulate the vestibular nerve to send information to the brain regarding the body's sense of balance or position.
The part of the brain located behind the right ear is the temporal lobe.

Ear Piercing hurts because they use a needle to make a hole in your ear but your nerves dont know that you want this done so they send signals to your brain telling your brain that something is inflicting damage upon you and your brain makes that part of you that is getting peirced send out signals which is pain.
