Tiny bones in the middle ear relay the eardrum's vibrations directly to the
A) oval window.
B) auditory canal.
C) vestibular sacs.
D) semicircular canals.
Oval Window
A membrane-covered opening that leads from the middle ear to the inner ear and is involved in the process of hearing.
Eardrum
A thin membrane that separates the outer ear from the middle ear and vibrates in response to sound waves.
Vestibular Sacs
Structures in the inner ear involved in maintaining balance and spatial orientation by detecting gravity and linear movement.
- Become familiar with the journey of sound waves from the external surroundings to the auditory cortex.
- Pinpoint the structures within the ear responsible for hearing and acquire knowledge on the operation of the middle ear.

Final Answer :
A
Explanation :
The three tiny bones in the middle ear (malleus, incus, and stapes) are responsible for relaying the vibrations from the eardrum to the oval window, which is the entrance to the inner ear. The vibrations are then transmitted through the fluid in the cochlea, ultimately leading to the stimulation of auditory nerve fibers and the perception of sound.
