Question

What process moves sound waves to the oval window? What is the function of the oval window?

When sound enters the ear, it first causes the eardrum to vibrate. This, in turn, causes the auditory ossicles to move, which causes sound
waves to move to the oval window through a process called
The oval window
Sound vibrations then enter the inner ear through the oval window.
First blank
A.sensorineural conduction
B.bone conduction
C. Air conduction
2nd blank
A separates the middle war from the inner ear
B separates the outer ear from the middle ear
C acts as an entrance to the cochlea
D helps the brain to maintain equilibrium

Answer 1

Bone conduction is the process that moves sound vibrations to the oval window, and the function of the oval window is to act as an entrance to the cochlea, separating the middle ear from the inner ear and transmitting sound vibrations into fluid pressure waves.

Step-by-step explanation:

The process that moves sound vibrations from the auditory ossicles to the oval window is known as bone conduction. When sound waves enter the ear and cause the eardrum to vibrate, these vibrations are transmitted through the three ossicles located in the middle ear. Eventually, the stapes connects with the oval window and pushes against it, transferring the sound vibrations into the fluid-filled cochlea of the inner ear.

The oval window functions as the boundary between the middle ear and the inner ear and acts as an entrance to the cochlea. It converts the mechanical vibrations from the stapes into pressure waves within the cochlear fluid, which then stimulate the hair cells positioned on the basilar membrane. This activity initiates the conversion of mechanical energy into electrical nerve impulses that are processed by the brain as sound.
