Respuesta :
The round window exists one of the two entrances from the middle ear into the inner ear. It exists closed by the secondary tympanic membrane (round window membrane), which vibrates with opposite phases to vibrations penetrating the inner ear through the oval window.
The round window dampens fluid vibrations.
What vibrates the round window?
A round window exists in one of the two openings into the cochlea from the middle ear. The round window membrane (RWM) vibrates with an opposite phase to acoustic vibrations joining the cochlea through the stapes at the oval window, another beginning of the cochlea to the center ear.
The round window helps to decompress acoustic energy that penetrates the cochlea through stapes movement against the oval window.
The round window exists one of the two entrances from the middle ear into the inner ear. It exists closed by the secondary tympanic membrane (round window membrane), which vibrates with opposite phases to vibrations penetrating the inner ear through the oval window.
