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

Tendons play a crucial role in the musculoskeletal system by attaching muscle to bone. This connection is vital for the function of muscles, as it allows the force generated by muscle contraction to be transmitted to the skeletal structure, facilitating movement at the joints. When a muscle contracts, it pulls on the tendon, which in turn pulls on the corresponding bone, resulting in movement. This synergy between muscles and bones is essential for various activities, including walking, running, and lifting.

The other options do not accurately describe the primary function of tendons. Tendons specifically serve to connect muscles to bones, whereas ligaments connect bone to bone, and muscles connect to muscle through different structures. Support for organ structure is related to different connective tissues rather than the specific role tendons play in facilitating movement through muscle-bone connections.
