ossicles ossicles the ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body. they serve to transmit sounds from the air to the fluid-filled labyrinth (cochlea). the absence of the auditory ossicles would constitute a moderate-to-severe hearing loss. the term "ossicle" literally means "tiny bone". though the term may refer to any small bone throughout the body, it typically refers to the malleus, incus, and stapes (hammer, anvil, and stirrup) of the middle ear. this article is one of a series documenting the anatomy of thehuman ear outer ear auricle ear canal middle ear tympanic membrane ossicles malleus incus stapes inner ear vestibules utricle saccule cochlea semicircular canals structure
