The ear

The outer ear collects sound and sends it down the ear canal to the eardrum, a thin skin that shakes when sound reaches it. Three tiny bones, the smallest in the body, pass the shaking on to the cochlea, a snail-shaped tube of liquid deep in the head. Its cells turn the shaking into messages that the hearing nerve carries to the brain.
