The malleus is a small bone in the human ear that plays a crucial role in hearing. It is also known as the hammer, given its resemblance to a tiny hammer when viewed under a microscope. Other synonyms for the malleus include the ossicle, incus, and stirrup. The ossicle is one of three tiny bones located in the middle ear, responsible for transmitting sound vibrations from the eardrum to the inner ear. The incus, or anvil-shaped bone, sits between the malleus and the stapes. The stirrup, or stapes, is the smallest bone in the human body and helps to amplify sound waves. Together, these three bones work in harmony to allow us to hear properly.
