What connects muscle to bone?

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

Answer: (A)

Muscles generate force that needs a bridge to the skeleton, and that bridge is the tendon. Tendons are dense regular connective tissue with collagen fibers aligned in the direction of pull, giving them the strength to transmit the muscle’s contraction to the bone. When the muscle shortens, the tendon pulls on the bone, producing movement at the joint. This is distinct from ligaments, which connect bone to bone to stabilize joints, cartilage, which cushions and reduces friction in joints, and bone itself, which is the rigid structure being moved. A familiar example is the Achilles tendon tying the calf muscles to the heel bone, enabling standing on tiptoe or pushing off during walking. The tendon–bone connection at the enthesis is specially adapted to handle the transfer of force between soft tissue and hard bone.
