What is the primary function of tendons in the musculoskeletal system?

The primary function of tendons in the musculoskeletal system is to attach muscles to bones. This connection is crucial because when muscles contract, they pull on the tendons, which in turn exert force on the bones, resulting in movement of the body. Tendons are made of strong, fibrous connective tissue that can withstand tension and are specifically designed to fulfill this role of linkage between muscular and skeletal systems, allowing for coordinated movements and stability during activities.

The other functions listed are associated with different structures. For instance, holding bones together at the joints is primarily the role of ligaments, which connect one bone to another and provide stability to joints. Providing cushioning between joints is a function of cartilage, which acts as a shock absorber and reduces friction. Facilitating joint movement is a broader function that involves many components of the musculoskeletal system, including synovial fluid, joint surfaces, and the muscles acting through their tendons but does not specifically define the role of tendons alone.
