Question

Which of the following statements is correct?

• A. Movable skull bone is mandible.
• B. We move our hands, while walking for balancing.
• C. Cartilaginous joints have little mobility due to fibrocartilage disc between its articular ends.
• D. All of the above.

Answer 1

The correct option is D

All of the above.

The mandible, or jawbone, is the only movable bone in the skull. It is the strongest and most massive bone in face. Swinging arms in opposing direction with respect to the lower limb reduces the angular momentum of the body, balancing the rotational motion produced during walking. Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint.
