Anatomy of the Ear

Your ear, from pinna to cochlear nerve is approximately 2-2.5 inches long.

Outer Ear: Sound waves are collected by the pinna, funneled down through the ear canal and hits the eardrum (tympanic membrane) causing it to vibrate.

Middle Ear: The vibrations from the eardrum send three little bones into action, transferring signals to a spiral-shaped shell/bony covered organ called the cochlea.

Inner ear: Tiny hair cells within the cochlea take the sound vibrations and transform them into electrical impulses that then travel to the brain.

I love how small yet intricately complex the ear can be. Did you know that the ear is not only responsible for hearing but also balance?
