The small oval-shaped hole between the middle ear and the inner ear connecting the stapes to the cochlea is the?

• A. Oval Window
• B. Round Window
• C. Eardrum
• D. Pinna

Answer: (A)

The oval window is the small membrane-covered opening that forms the bridge between the middle ear and the inner ear. The stapes fits into this window and pushes on it when sound vibrations travel through the ear from the eardrum via the middle-ear bones. That piston-like movement creates waves in the fluid of the cochlea, triggering the hair cells to convert mechanical energy into neural signals. The round window is a separate opening that relieves pressure in the cochlea, not the direct connection point for the stapes. The eardrum (tympanic membrane) is the outer-to-middle-ear boundary that first vibrates in response to sound, and the pinna is the external part of the ear that helps collect sound. So the oval window is the correct connection between the middle ear and the inner ear.
