What is the role of cartilage in joint movement?

To increase friction between bones
To allow bones to grow
To reduce friction during movement
To connect muscles to bones

The correct answer is: To reduce friction during movement

Cartilage plays a crucial role in joint movement by functioning as a smooth, flexible tissue that reduces friction between the bones in a joint. This allows the bones to glide over one another more easily during movement, which is essential for smooth and fluid motions, such as bending and twisting. The presence of cartilage prevents wear and tear on the bone surfaces, helps to absorb shock, and contributes to the overall stability of the joint. This is especially important in weight-bearing joints like the knees and hips, where the forces can be substantial. By minimizing friction, cartilage not only supports efficient movement but also helps to protect the bones from damage over time.
