Stapes

The stapes is one of the three small bones, known as ossicles, located in the middle ear. It plays a crucial role in hearing by receiving vibrations from the other ossicles and transmitting them to the inner ear by pressing against the oval window of the cochlea.

  • A medical condition causes the three small bones in the middle ear to become rigid and unable to move freely in response to sound. What is the most direct consequence of this condition on the process of hearing?

Learn After
  • A patient is diagnosed with a specific type of conductive hearing loss. Medical imaging reveals that sound vibrations are correctly transmitted from the eardrum through the first two small bones of the middle ear, but the vibrations are not effectively passed on to the fluid-filled inner ear. This failure to transmit the mechanical energy results in muffled hearing. Which structure is most likely the source of the problem?
