The rigid structures that make up the skeleton, providing support and protection for internal organs, and facilitating movement with muscles, are known as what?

• A. Tendons
• B. Cartilage
• C. Skeletal bones
• D. Muscular tissue

Answer: (C)

Rigid frameworks of the body—the bones that form the skeleton—provide support, protect internal organs, and act as levers for movement when muscles contract. The bones are mineral-rich, making them strong and rigid, which lets them support the body’s weight and shield vital organs like the brain, heart, and lungs. They also create joints that muscles pull against, translating muscle contraction into motion. Tendons connect muscles to bones, enabling the transfer of force but they are not the rigid framework themselves. Cartilage cushions and smooths joints, reducing friction, yet it isn’t the hard, protective structure of the skeleton. Muscular tissue forms the muscles that generate movement, but without the bones to anchor and leverage them, movement wouldn’t be possible.
