What is the primary role of tendons?

The primary role of tendons is to connect muscles to bones. Tendons are strong, fibrous tissues that serve as the link between muscle contractions and the movement of bones at joints. When a muscle contracts, it pulls on the tendon, which then translates that pull into movement of the bone, allowing for joint motion and muscle function.

Understanding the context of other connective tissues can clarify why option A is the correct choice. Ligaments, for instance, connect bones to other bones, playing a critical role in stabilizing joints. Cartilage, another type of connective tissue, provides cushioning and support within joints, which helps in reducing friction during movement. Muscle fascia surrounds muscles to provide support and protection, but it does not serve to connect muscles to bones as tendons do. Thus, the specific function of tendons in linking muscles to bones is essential for physical movement and overall body mechanics.
