The structures of the inner ear are responsible for both hearing and balance. True or False?

• A. True
• B. False
• C. Only for hearing
• D. Only for balance

Answer: (A)

The statement is true because the inner ear contains two primary structures that serve distinct functions: the cochlea and the vestibular apparatus. The cochlea is responsible for the sense of hearing; it converts sound vibrations into nerve impulses that are transmitted to the brain. On the other hand, the vestibular apparatus, which includes the semicircular canals and vestibule, is responsible for maintaining balance and spatial orientation by detecting changes in head position and motion. This dual functionality confirms that the structures of the inner ear are indeed involved in both hearing and balance, making the answer true. The other options focus solely on one aspect (hearing or balance) or deny any involvement, but the interconnected nature of these structures clearly facilitates both functions.
