Where the connecting medium is hyaline cartilage, a cartilaginous joint is termed a synchondrosis or primary cartilaginous joint. They provide stability to the skeletal system as well as allowing for specialized movement. A temporary synchondrosis is the epiphyseal plate (growth plate) of a growing long bone. Hyaline cartilage is the most common of all the cartilages present in the body. The bursal fluid, exuded by the synovial membrane, is called synovia, hence the common name for this class of joints.
