Full Bones of the Ear Description
[Continued from above] . . . vibrations to the incus from the eardrum. The anvil (incus) has a broad joint with the hammer and a very delicate joint to the stirrup (stapes). The incus sends the sound vibrations that the malleus transmitted, over to the stapes. From here, the stapes sends those vibrations to the inner ear's membranes. The base of the stirrup fills the oval window, which leads to the inner ear.
The inner ear receives sound waves from these ossicles. The small bones create fluid membrane waves by converting compression sound waves from the eardrum.
