The auditory ossicles are composed of which three bones?

Explanation:
Sound vibrations are transmitted by three tiny middle-ear bones—the malleus, incus, and stapes. These form the auditory ossicles, a lever system that moves vibrations from the eardrum (tympanic membrane) to the inner ear by pushing on the oval window. The tympanic membrane is a membrane, not a bone, and the pinna is part of the outer ear, so they aren’t part of the ossicular chain. Therefore, the trio that makes up the auditory ossicles is malleus, incus, and stapes.
