How do tendons primarily assist in movement?

Tendons play a crucial role in facilitating movement by connecting muscles to bones. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone, creating movement at the joint. This connection is integral to the biomechanics of the body, as it enables the translation of muscular force into skeletal motion.

The other options, while relevant to musculoskeletal function, do not accurately describe the primary role of tendons. Tendons do not absorb shock; that function is typically associated with ligaments and certain joint structures. Additionally, the attachment of bones to other bones is the role of ligaments, not tendons. Lastly, the production of synovial fluid is a function of synovial membranes within joints, unrelated to the role of tendons. Thus, the vital function of tendons in enabling movement through their connection of muscles to bones solidifies option C as the correct choice.
