Question

What are the functions of malleus,incus and stapes?

Answer 1

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


Stapes: A stirrup-shaped bone in the middle ear. The stapes transmits sound vibrations from the incus, another little bone in the middle ear, to the oval window adjacent to the inner ear. The stapes is the smallest bone in the body.

Function. The malleus is one of three ossiclesin the middle ear which transmit sound from the tympanic membrane (ear drum) to the inner ear. The malleus receives vibrations from the tympanic membrane and transmits this to the incus.
