What is the primary function of a tendon?

The primary function of a tendon is to connect muscle to bone. Tendons are dense, fibrous connective tissues that serve as a vital link between muscles, which generate force, and the bones, which transmit that force to facilitate movement. When a muscle contracts, the generated force is transmitted through the tendon to the bone, resulting in motion at the joint. This connection is critical for normal movement and coordination in the musculoskeletal system.

The other choices represent different structures and functions that are not associated with tendons. For instance, the connection between bones is facilitated by ligaments, while joint movement support is more aligned with adjacent structures like cartilage and ligaments. Additionally, the covering and separation of muscles pertain to fascia, not tendons. Understanding this distinction highlights the unique role tendons play in the movement and function of the body.
