The transduction of sound waves into action potentials occurs
a. within the tectorial membrane as it is stimulated by the hair cells.
b. when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons.
c. as the basilar membrane vibrates at different frequencies in response to the varying volume of sounds.
d. within the middle ear as the vibrations are amplified by the malleus, incus, and stapes.

ANSWER:
Step 1 of 2
The journey of sound transduction is captivating. Where does this transformation take place? Is it within the tectorial membrane (Option A), as it is stimulated by the hair cells?. Sound waves start by entering our outer ear and are channeled down the auditory canal, colliding with the eardrum. These vibrations get an enhancement in the middle ear by three specific bones: malleus, incus, and stapes. However, is this where sound transduction actually begins (Option D)? Let's delve further.
From there, these boosted vibrations are directed to the cochlea in the inner ear, a chamber filled with fluid. Inside the cochlea, a unique structure, the basilar membrane, vibrates differently according to various sound intensities. This might be where the transformation occurs (Option C), but let's continue our exploration.
