Stapes Bone - Inner Ear Bones (Auditory Ossicles)

What is the stapes bone? The stapes bone is a stirrup shaped auditory ossicle that transmits sound waves from the incus to the cochlea of the inner ear.

Anatomical structures of the Stapes Bone:

Base of Stapes

Head of Stapes

Neck of Stapes

Posterior Limb of Stapes

Anterior Limb of Stapes

Base of Stapes

The base or footplate of the stapes fits into the fenestra vestibuli on the medial wall of the tympanic cavity. A ring of ligamentous fibers, annular ligament, attaches the margins of the footplate and the fenestra.
Anterior and posterior limbs connect the neck to the base (footplate) of the stapes.
