Malleus

Template:Infobox Bone

Overview[edit | edit source]

The malleus or hammer is a hammer-shaped small bone or ossicle of the middle ear which connects with the incus and is attached to the inner surface of the eardrum. The word is Latin for hammer.

It transmits the sound vibrations from the eardrum to the incus.

The malleus is unique to mammals, and evolved from a lower jaw bone in basal amniotes called the articular, which still forms part of the jaw joint in reptiles.
