The Cellular Membrane Across Which Ion Flow Varies During Auditory

Question

The cellular membrane across which ion flow varies during auditory transduction is the
A)tectorial membrane.
B)tympanic membrane.
C)round-window membrane.
D)hair cell membrane.
E)basilar membrane.

Accepted Answer

The cellular membrane across which ion flow varies during auditory transduction is the hair cell membrane, which is found in the cochlea of the inner ear. It is responsible for converting mechanical vibrations of sound waves into electrical signals that are then transmitted to the brain. The tectorial membrane, tympanic membrane, round-window membrane, and basilar membrane all play important roles in the auditory system, but they are not directly involved in the transduction process that occurs at the hair cell membrane.
