The transmission of sound vibrations through the internal ear occurs chiefly through (a) nerve fibers, (b) air, (c) fluid, (d) bone.
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 neurotransmitterthat stimulates sensory neurons.(C) as the basilar membrane vibrates at different frequenciesin response to the varying volume of sounds.(D) within the middle ear as the vibrations are amplified by themalleus, incus, and stapes
(a) choose one part of the auditory conductive mechanism--the outer ear or middle ear--and describe how sound is transduced (changed from acoustic energy to mechanical energy) through that part of the auditory system, and
(b) comment on how the anatomy of that part of the ear enables normal auditory conductive physiology.
