Question

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 depolarize the, release of neurotransmitter molecules that stimulate 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 1

The correct option is B when hair cells are bent against the tectorial membrane, causing them to depolarize the, release of neurotransmitter molecules that stimulate sensory neurons

The organ of balance is found inside the inner ear. It is made up of three semicircular canals and two otolith organs. Cochlear region is where transduction of sound takes place. Each semicircular canals end in a space that has small hair cell in it.

So, the correct option is 'When hair cells are bent against the tectorial membrane, causing them to depolarize the release of neurotransmitter molecules that stimulate sensory neurons'.
