What is the role of the articular cartilage in the skeletal system?

The articular cartilage plays a crucial role in the skeletal system by primarily reducing friction between bones at the joints. This smooth, slippery tissue covers the ends of bones where they articulate, allowing for easier movement and flexibility during activities such as walking, running, and bending. By minimizing friction, articular cartilage not only makes movement smoother but also protects the underlying bone surfaces from wear and tear, which can lead to joint pain and issues like osteoarthritis.

While stabilizing bones, connecting muscles to bones, and producing blood cells are essential functions within the skeletal system, they are not the primary roles of articular cartilage. Stabilization often involves ligaments and tendons, which help maintain joint integrity, while the connection of muscles to bones is managed through tendons. Blood cell production occurs in the bone marrow, a separate aspect of the skeletal system's function. Thus, the primary function of articular cartilage, which is to reduce friction, supports efficient joint movement and protects joint health.
