Which part continues vibrations to the auditory nerve?

Which part continues vibrations to the auditory nerve?

• A. Inner ear
• B. Cochlea
• C. Semicircular canals
• D. Vestibule

Answer: (A)

Vibrations become neural signals through the inner ear, specifically in the cochlea. When the fluid inside the cochlea moves, the hair cells in the organ of Corti bend and convert this mechanical energy into electrical signals. These signals are carried by the auditory (vestibulocochlear) nerve to the brain, enabling hearing. The semicircular canals and vestibule mainly handle balance and head position, not the transfer of vibrations to the auditory nerve. So, the cochlea is where vibrations are continued into neural impulses for hearing.
