Definition
  1. Noun:
    • The stirrup-shaped ossicle that transmits sound from the incus to the cochlea: The "stapes" is the smallest and innermost of the three tiny bones (ossicles) in the middle ear. Its distinctive stirrup shape allows it to function as a vital link in the chain of bones that conducts sound vibrations from the eardrum to the inner ear.
Usage Examples

    • The stapes is the smallest bone in the human body.
    • Otosclerosis is a condition that can cause the stapes to become fixed, leading to hearing loss.

Advanced Usage
  • Surgical Context: The "stapes" is often discussed in medical contexts, particularly in relation to otology (the study of the ear).
    • The surgeon performed a stapedectomy to replace the diseased stapes with a prosthesis.
Variants and Related Words

  • Stapedectomy (n): A surgical operation to remove the stapes.
  • Ossicle (n): A general term for a small bone, specifically referring to the three bones of the middle ear (malleus, incus, stapes).
Synonyms

Related Terms (Not Phrasal Verbs or Idioms)

  • Malleus: The hammer-shaped first ossicle.
  • Incus: The anvil-shaped middle ossicle.
