Which structure helps bring stability to joints?

Ligaments are essential structures that provide stability to joints by connecting bones to one another. They are composed of dense connective tissue, which gives them the strength and resilience needed to withstand the forces that act on joints during movement. By holding bones together, ligaments help maintain proper alignment and prevent excessive movement that could lead to dislocations or injuries. This stability is crucial for the overall function of the musculoskeletal system during activities such as walking, running, or any form of physical exertion.

Tendons, while important for facilitating movement by connecting muscles to bones, do not primarily stabilize joints. Cartilage contributes to joint function by providing a smooth surface for joint movement and absorbing shock, but it does not connect bones in the way that ligaments do. Mucus, while it has various functions in the body, including lubrication in certain systems, does not play a role in stabilizing joints. Therefore, ligaments are specifically designed to serve the purpose of joint stability, which makes them the correct choice in this context.
