Tendons are dense sheets of connective tissue composed primarily of collagen fibers, serving to anchor muscle to bone and facilitating movement. These specialized structures transmit the mechanical force generated by muscle contraction across a joint to the skeleton. The composition of tendons provides tensile strength necessary to withstand significant pulling forces while remaining flexible enough to articulate within the body's complex biomechanical system. Their function is crucial for locomotion and maintaining the physical structure and stability of the musculoskeletal system.
