JudyThe oval window is a membrane-covered opening between the middle and inner ear that transfers sound vibrations from the middle ear to the inner ear. The round window is another membrane-covered opening in the inner ear that allows for the dissipation of sound energy and equalization of pressure.

Acts as a pressure relief valve for fluid in the ear?
The Eustachian tube acts as a pressure relief valve for fluid in the ear by equalizing the pressure between the middle ear and the back of the nose and throat. When the pressure on either side of the eardrum is balanced, it helps prevent discomfort and potential complications such as ear infections.
What part of the ear transfers sound vibrations to the cochlea?
The cochlea receives sound vibrations from the middle ear via the oval window, which is connected to the stapes bone. The stapes bone vibrates against the oval window, creating fluid motion within the cochlea that stimulates the hair cells responsible for hearing.
