The stapes is one of the three small bones of the middle ear. It transmits sound vibrations from the incus bone to the oval window of the cochlea. It is nicknamed the stirrup bone because it is shaped like a stirrup. The three bones of the middle ear are collectively called the ossicles. If the stapes or one of the other ossicles is not functioning, a conductive hearing loss will result.
