The Transduction of Sound Waves into Action Potentials by the Human

question 39

Multiple Choice

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
