Definition[Bearbeiten]
In veterinary medicine, stapes' refers to one of the three auditory ossicles (ossicula auditus) alongside the malleus (hammer) and incus (anvil). Together they serve to transmit sound from the eardrum (membrana tympani) to the inner ear (auris interna).
Anatomy[Bearbeiten]
The stapes consists of several components:
- Caput stapedis (head): is in articulated connection with the lenticular bone (Os lenticulare) (Articulatio incudostapedia)
- Base stapedis (foot plate): is inserted into the vestibular window (fenestra vestibuli) and attached to its edge by the anular stapedis ligament
- two crura (legs): sit on the foot plate
A membrane (membrana stapedis) is stretched between the foot plate and the two legs.
