So the way we hear is when sound comes and travels down the ear canal, it vibrates the eardrum. The fancy term for it is the tympanic membrane. That sets in motion the smallest bones in the body. They're called the malleus, incus, and stapes, which is Latin for the hammer, the anvil, and the stir bone. As they vibrate, they set in motion fluids in the inner ear, and this is where these incredibly delicate sensory cells reside.
