The transduction of sound waves to action potentials takes place ________.
- 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 depolarized and release neurotransmitter molecules that stimulate sensory neurons
- C as the basilar membrane becomes more and depolarizes, initiating an action potential in a sensory neuron
- D as the basilar membrane vibrates at different frequencies in response to the varying volume of sounds
- E within the middle ear as the vibrations are amplified by the malleus, incus, and stapes
