Which statement best describes the auditory ossicle?

• A. The outer ear cartilage
• B. The nerve that carries sound to the brain
• C. The small bones in the middle ear that transmit sound
• D. The outer ear canal

Answer: (C)

The auditory ossicles are the small bones in the middle ear that transmit sound. They form a tiny lever chain—the hammer, anvil, and stirrup—that moves vibrations from the eardrum to the inner ear’s oval window. This transmission also helps match the air vibrations to the fluid-filled inner ear, ensuring efficient hearing. The outer ear cartilage and outer ear canal belong to the external ear, and the nerve that carries sound to the brain is the auditory nerve, not a bone.
