The transduction of sound waves into action potentials occurs ________.
A) in the tectorial membrane as it is stimulated by 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

Question

Quizplus · Accepted Answer

The transduction of sound waves into action potentials occurs when hair cells in the cochlea are bent against the tectorial membrane. This bending causes the hair cells to depolarize and release neurotransmitters that stimulate the sensory neurons, leading to the generation of action potentials that are interpreted by the brain as sound.
