Definition

1. Noun:
   • A specific anatomical opening in the ear: The "round window" is a membrane-covered opening in the inner ear, specifically in the cochlea. It functions to allow fluid movement within the cochlea in response to sound vibrations transmitted by the stapes bone at the oval window.

Usage Examples

• Noun:
  • The vibration of the stapes at the oval window creates a pressure wave in the cochlear fluid, which is dissipated at the round window.
  • A rupture of the round window membrane can lead to hearing loss and vertigo.

Advanced Usage

• "Round window niche": The bony recess in which the round window is located.
  • The surgeon carefully examined the round window niche before proceeding.

Variants and Related Words

• Oval window (n): The other opening from the middle ear into the inner ear, where the stapes bone attaches. It works in conjunction with the round window.
• Cochlear window: An alternative, less common name for the round window.
• Fenestra cochleae: The formal Latin anatomical term for the round window.

Synonyms

• Fenestra rotunda: The Latin synonym for "round window."

Related Terms (Conceptual)

• Perilymph: The fluid in the cochlea whose movement is facilitated by the round window.
