What structure connects bone to muscle?

1. Tendons

2. Ligaments

3. Cartilage

4. Synovial fluid

The correct answer is: Tendons

Tendons are the structures that connect bone to muscle. They are composed of dense connective tissue that transmits the force generated by muscles to the bones, enabling movement at joints. When a muscle contracts, it pulls on the tendon, which in turn pulls on the associated bone, resulting in motion. The strength and flexibility of tendons are crucial for effective movement and stability. In contrast, ligaments connect bone to bone, providing stability to joints by preventing excessive movement. Cartilage serves as a cushion and smooth surface for joint movement, while synovial fluid lubricates joints to reduce friction during movement. Each of these tissues has its own specific role in the musculoskeletal system, but tendons are uniquely responsible for linking muscles to bones.
