The semicircular canals are part of the inner ear and help to maintain balance.

• A. True
• B. False
• C. They are part of the outer ear
• D. They are bone marrow cavities

Answer: (A)

The semicircular canals are structures in the inner ear that detect rotational head movements by sensing fluid motion inside them and signal the brain to help maintain balance and spatial orientation. This means the statement that they help to maintain balance is true, since they are part of the inner ear’s vestibular system. They are not part of the outer ear, and they are not bone marrow cavities, which are located inside bones and have no role in balance.
