The Transduction of Sound Waves into Action Potentials by the Human

The transduction of sound waves into action potentials by the human ear 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 depolarize and release neurotransmitter that stimulates sensory neurons
C) as the basilar membrane becomes more permeable to sodium ions 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
