How does the ear work

The outer ear collects the sounds and takes them through the auditory canal towards the eardrum. The sound waves produce the vibration of the eardrum. The ossicles of the middle ear (malleus, incus and stapes) transmit and amplify the vibrations into the inner ear. In the inner ear there is a liquid that stimulates the nerve endings (hair cells). Hair cells send electrical impulses through the auditory nerve towards the brain.
