Function Of Cartilage In Musculoskeletal System Quiz
A Cartilage is a smooth and flexible tissue that covers out joints. If one has healthy cartilage, they can move more easily as joints will just glide each other during motion with minimum friction. Test your knowledge of the function of Cartilages in the musculoskeletal system by taking the quiz below.
