Question

Quizplus · Accepted Answer

The bending of the cilia of the inner hair cells in the cochlea causes a release of small bursts of neurotransmitter. This neurotransmitter release stimulates the auditory nerve fibers and sends signals to the brain for auditory processing. The outer hair cells, on the other hand, function to amplify the movement of the basilar membrane and play a role in the cochlear reflection. The tectorial membrane is a gel-like structure that overlies the hair cells and plays a role in stimulating the cilia by moving back and forth in response to sound waves. The apex of the cochlea is the part of the cochlea furthest away from the oval window and is responsible for processing low frequency sounds.
