What is the primary function of tendons?

• A. Attach muscles to bones and transmit force
• B. Store calcium
• C. Produce synovial fluid
• D. Lubricate joints

Answer: (A)

Tendons are the tough, collagen-rich bands that connect muscle to bone, and their main job is to transmit the force generated by a muscle contraction to the skeleton so movement can occur. They act as the bridge that converts muscular effort into skeletal motion, while also helping to stabilize joints as the limb moves. They don’t store calcium—that’s a role of bone—nor do they produce or lubricate joints, which is handled by synovial fluid produced by the joint’s synovial membrane.
