Which correctly traces the path of a sound vibration?
A) auditory canal → tympanic membrane → malleus → incus → stapes → oval window → cochlea → cochlear nerve
B) auditory canal → malleus → incus → stapes → tympanic membrane → oval window → cochlea → cochlear nerve
C) auditory canal → tympanic membrane → malleus → incus → stapes → cochlea → oval window → cochlear nerve
D) auditory canal → tympanic membrane → oval window → cochlea → malleus → incus → stapes → cochlear nerve
E) auditory canal → malleus → incus → stapes → oval window → tympanic membrane → cochlea → cochlear nerve
Cochlear Nerve
A nerve that transmits sound information from the cochlea in the inner ear to the brain.
Tympanic Membrane
Also known as the eardrum, it is a thin membrane that separates the outer ear from the middle ear and vibrates in response to sound waves.
Oval Window
A membrane-covered opening that leads from the middle ear to the inner ear, transmitting sound vibrations to the cochlea.

Final Answer :
A
Explanation :
The correct path of a sound vibration starts at the auditory canal, then moves to the tympanic membrane (eardrum), through the ossicles (malleus, incus, stapes), to the oval window, into the cochlea, and finally to the cochlear nerve. This sequence accurately describes how sound waves are transmitted from the outer ear through the middle ear and into the inner ear where they are converted into nerve impulses.
