What does the stirrup do?

The stapes or stirrup is a bone in the middle ear of humans and other animals which is involved in the conduction of sound vibrations to the inner ear.

Because of its shape, it's sometimes called the stirrup. While it's the smallest bone in the body, it has the important role of translating movement from the eardrum to fluids in the inner ear, causing sound waves to be changed into nerve impulses that are translated in the brain.
