What is the main function of cartilage in joints?

The primary function of cartilage in joints is to provide cushioning and support. Cartilage is a dense, flexible tissue that acts as a protective layer between the bones that come together at a joint. This cushioning effect allows for smooth movement during joint motions and helps to absorb shock, thereby reducing the risk of injury to the bones and surrounding tissues during activities such as walking, running, and jumping.

In addition to cushioning, cartilage also contributes to the overall stability of the joint, allowing for a range of motion while maintaining structural integrity. It helps facilitate smooth and pain-free joint movement, which is crucial for overall joint function. This role of cartilage is vital not only for daily activities but also for athletic performance, making it an essential component of a healthy musculoskeletal system.
