Malleus, also known as the hammer bone, is a critical element in the human ear responsible for transmitting sound vibrations to the inner ear. It is a small bone, shaped like a tiny hammer, that sits within the middle ear. Malleus or hammer is a commonly used term in anatomy, but there are some synonyms that can also be used to describe this vital bone. These synonyms include incus (anvil), stapes (stirrup), auditory ossicles (hearing bones), and ossicular chain (a chain of three bones consisting of malleus, incus, and stapes). Understanding synonyms for malleus or hammer is vital, especially when describing the anatomy of the human ear.
