What is the function of inner hair cells?

The function of inner hair cells is to send information to the brain. These specialized sensory cells are located in the cochlea of the inner ear and play a crucial role in the auditory system. Inner hair cells convert sound vibrations into electrical signals, which then travel along the auditory nerve to the brain for processing. This process is essential for hearing, as it allows the brain to interpret sound frequencies and intensities.

The role of inner hair cells is particularly significant, as they are responsible for the majority of auditory perception. They are stimulated by the movement of fluid within the cochlea that occurs due to sound waves, leading to the release of neurotransmitters that signal the auditory nerve fibers.

While other components of the auditory system are involved in different functions, such as amplifying sounds or aiding in balance, inner hair cells primarily serve to transmit auditory information to the brain, making option B the correct choice.
