1) Eardrum
2) Perilymph
3) Oval window
4) Bony ossicles
5) Eighth cranial nerve?
A) 1, 5, 2, 4, 3
B) 1, 3, 4, 2, 5
C) 1, 2, 4, 5, 3
D) 1, 4, 3, 2, 5
Perilymph
The fluid located within the labyrinth of the inner ear, playing a crucial role in hearing and balance.
Bony Ossicles
Small bones, often found in the middle ear, that aid in hearing.
Oval Window
A membrane-covered opening that connects the middle ear to the inner ear, facilitating the transmission of sound vibrations.

Final Answer :
D
Explanation :
Vibration of the eardrum transmits through the bony ossicles. Vibrations at the oval window transmit in perilymph within the inner ear to stimulate hair cells that send impulses along the eighth cranial nerve to the brain.
