How does the middle ear amplify sound?
The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles. The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea).
How does the inner ear work?
The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move. The movement of the fluid in the inner ear causes the hair cells in the cochlea to bend.
What does the middle ear control?
The middle ear’s function is to transmit sound from the outer ear to the inner ear.
How does the middle ear drain?
The ear has a space behind the ear drum called the middle ear. The lining of this space makes a fluid to keep the tissues moist. This fluid drains through a little tube (eustachian tube) that runs to the back of the nose.
How sound travels through the ear to the brain?
The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.
How do you know if your inner ear is damaged?
Signs and Symptoms When the inner ears are injured, you may experience: Vertigo (you feel like the room or you are spinning). Dizziness (you feel light-headed). Unsteadiness (you feel off-balance when walking or standing).

What triggers vestibular balance disorders?
Vestibular dysfunction is most commonly caused by head injury, aging, and viral infection. Other illnesses, as well as genetic and environmental factors, may also cause or contribute to vestibular disorders. Disequilibrium: Unsteadiness, imbalance, or loss of equilibrium; often accompanied by spatial disorientation.
How can I clear my Eustachian tube naturally?
Blocked eustachian tubes often get better on their own. You may be able to open the blocked tubes with a simple exercise. Close your mouth, hold your nose, and gently blow as if you are blowing your nose. Yawning and chewing gum also may help.
Will fluid behind eardrum go away?
or liquid behind the ear drum without symptoms of infection. Is it possible that the ear fluid will just go away on its own? Fluid often goes away on its own, so your doctor will often recommend watchful waiting for the first 3 months. Be sure to follow-up with your doctor to make sure the fiuid goes away completely .
What fills the middle ear?
The middle ear or tympanic cavity is an irregular, laterally compressed space within the temporal bone. It is filled with air, which is conveyed to it from the nasal part of the pharynx through the auditory tube.
What separates the middle ear and the inner ear?
The tympanic membrane or eardrum is a thin membrane that separates the outer ear canal from the middle and inner ear. The middle ear contains the three tiniest bones in the body, the malleus , incus and stapes , more commonly referred to as the hammer, anvil, and stirrup.
What is the middle ear component involved with sound?
The middle ear is the part of the ear between the eardrum and the oval window. The middle ear transmits sound from the outer ear to the inner ear. The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustrachian tube.
