Once the last bone (the stapes) vibrates, it hammers up and down at a space called the oval window in the cochlea of the inner ear. The cochlea is filled with a fluid, and the vibrations of the stapes send pressure waves through the fluid. There is a membrane in the cochlea that is bent back and forth in different places based on the intensity of the sound, and the bending of the membrane causes small hair-like stereocillia to bend and send an electrical impulse to the brain to be interpreted as sound.

6 The function of the eardrum in the middle ear is to?
The eardrum, or tympanic membrane, in the middle ear serves to transmit sound waves from the outer ear to the ossicles (small bones in the ear) for further amplification and transmission to the inner ear. It also helps to protect the delicate structures of the inner ear.
Do human ears have bones?
Yes, human ears have three small bones called the ossicles: the malleus, incus, and stapes. These bones help transmit sound vibrations from the eardrum to the inner ear.
How does the eardrum work?
The eardrum, also known as the tympanic membrane, is a thin membrane that vibrates in response to sound waves. These vibrations are transmitted through the middle ear bones to the inner ear, where they are converted into electrical signals that are sent to the brain for interpretation as sound.
What is the purpose of tympanoplasty?
to repair the perforated eardrum, and sometimes the middle ear bones (ossicles) that consist of the incus, malleus, and stapes.Tympanoplasty is performed to reconstruct the eardrum after partial or total conductive hearing loss, usually caused by chronic middle ear infections, or perforations that do not heal
How does the external auditory canal transmit sound waves to the inner ear?
The external auditory canal collects sound waves and funnels them towards the eardrum. The eardrum vibrates in response to the sound waves, which then transmit the vibrations to the three small bones in the middle ear. These bones amplify the vibrations and send them to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for interpretation.
Do otoscopes use a puff of air?
Some otoscopes can deliver a small puff of air to the eardrum to see if the eardrum will vibrate
Does sound go through your ears?
Yes, sound is recognized by the brain through your ears. When you hear a sound, it enters the ear canal to the eardrum. The eardrum causes small bones to vibrate, which causes tiny hairs to send signals to the brain.
What are the 3 small bones from the eardrum called?
occicles
How sound waves affect the eardrum?
Sound waves cause the eardrum to vibrate, which in turn moves the ossicles (small bones in the middle ear). These vibrations are then transmitted to the cochlea in the inner ear, where they are converted into electrical signals that travel to the brain, allowing us to perceive sound.
What are the three small bones linked together to connect to the eardrum to the inner ear?
auditory ossicles
What is the anvil in your ear used for?
Sound travels by vibrating things. First the molecules in the air vibrate. This makes the ear drum vibrate. This makes three small bones vibrate. The three bones are the anvil, hammer and the stirrup.

What are the small bones that transmit sound waves from the eardrum to the inner ear?
the bones pick up the movement/vibration of the eardrum which is caused by movement of air. between the movement of these three bones the sound vibration is amplified in intensity. the bones then move via the stapes in the oval window, causing movement of the fluid in the cochlea which then transmits this to the auditory nerve to the brain. so the bones help in the transformation of airborne vibration/movment into a mechanical signal and ultimately an electrical signal to transmit to the brain
How does the sound travel in your ear?
Sound waves enter the ear canal and cause the eardrum to vibrate. These vibrations are transmitted through the three small bones in the middle ear, which amplify the sound. The vibrations then travel to the cochlea in the inner ear, where they are converted into electrical signals that are sent to the brain for processing.
What happens when a sound wave hits a small thin membrane?
When a sound wave hits a small thin membrane, the membrane will vibrate in response to the varying pressure of the sound wave. This vibration will produce sound waves on the other side of the membrane, essentially transmitting the original sound.
The function of the eardrum in the middle ear is to A- carry the sound energy to the brain B- collect the sound waves C- amplify the received sound D- vibrate with the frequency of the received sound?
D- The eardrum in the middle ear vibrates with the frequency of the received sound. These vibrations are then transmitted to the small bones in the middle ear, which amplify and transmit the sound to the inner ear for further processing.
