Which structure attaches bone to bone?

• A. Ligament
• B. Tendon
• C. Cartilage
• D. Fascia

Answer: (A)

The thing that attaches bone to bone is the ligament. Ligaments are strong bands of connective tissue that span joints, tying the bones together to provide stability and guide movement. They resist tearing by handling tensile forces and help limit excessive motion to protect the joint.

Tendons, by contrast, attach muscle to bone to transmit muscle force for movement. Cartilage coats the ends of bones at joints to reduce friction and absorb shock, but it doesn’t connect bones. Fascia is connective tissue that surrounds and supports muscles and other structures, not a direct link between bones. So, ligaments are the structures that connect bone to bone.
