a. Inner Hair Cells: The primary function of the inner hair cells is to transmit sound information. They convert the mechanical vibrations caused by sound waves into electrical signals, which are then sent to the brain via the auditory nerve. This process is known as mechanotransduction. There are approximately 3,500 inner hair cells in each ear, and each one is connected to several nerve fibers that carry the signals to the brain.

b. Outer Hair Cells: The outer hair cells serve a different function. They act as amplifiers to enhance the sound signals received by the inner hair cells. When the outer hair cells receive a signal, they change shape, which amplifies the movement of the basilar membrane and thus enhances the signal that is sent to the inner hair cells. There are about 12,000 outer hair cells in each ear. They are also involved in the process of otoacoustic emissions, sounds that are generated within the inner ear and can be measured with a sensitive microphone placed in the ear canal.
