Description

Ossicles: malleus( hammer), incus (anvil), and stapes(stirrup) are the three smallest bones that are joined together to form assembly located in the middle ear section working together to transmit incoming sound wave from external auditory meatus, from the tympanic membrane to inner ear by mechanically amplifying the sound. inner ear. loud noise can damage inner ear which must be protected, which is achieved by stapedius muscle, causing the stapes to tilt for a short time, thus transmitting sound partially. Tensor tympani muscle provides additional protection to ossicles if they are shaken too vigorously, by sticking to malleus and tightening the eardrum. In this model, you can see an enlarged ossicular assembly, created using CT data showing all the minute details.
