The adjacent bones are united by cartilage in the cartilaginous bones which is a tough but flexible type of connective tissue. These types of joints lack a joint cavity and involve bones that are joined together by either hyaline cartilage or fibrocartilage. There are two types of cartilaginous joints. A synchondrosis is a cartilaginous joint where the bones are joined by hyaline cartilage. The second type of cartilaginous joint is a symphysis, where the bones are joined by fibrocartilage.
A cartilaginous joint where the bones are joined by fibrocartilage is called a symphysis. Fibrocartilage is very strong because it contains numerous bundles of thick collagen fibres, thus giving it a much greater ability to resist pulling and bending forces when compared with hyaline cartilage. Some examples of cartilaginous joints are Sternocostal joint, Epiphyseal growth plates in children. The sternum bone, and Sacrococcygeal joint
