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

Articular cartilage serves several essential functions in the skeletal system, particularly in relation to joints. Its primary role is to cover the surfaces of bones where they meet to form joints, creating a smooth, low-friction surface that facilitates movement. This structure allows bones to glide over one another during motion, reducing wear and tear and minimizing the risk of damage. The presence of articular cartilage is critical for maintaining joint health and function, as it helps absorb some of the impact experienced during activities such as walking or running, providing cushioning in addition to its role in covering joint surfaces. By maintaining a healthy layer of articular cartilage, joints can function more effectively and with less pain or stiffness, illustrating its importance in the overall mechanics of the skeletal system.
