The incus // is a bone in the middle ear. The anvil-shaped small bone is one of three ossicles in the middle ear. The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes, medially. The incus is so-called because of its resemblance to an anvil (Latin: Incus).
The incus is the second of the ossicles, three bones in the middle ear which act to transmit sound. It is shaped like an anvil, and has a long limb and a short limb that protrude from the point of articulation with the malleus.:862
