Joints have been classified into three major structural forms (i) Fibrous joints don’t allow any movement. This type of joint is shown by flat skull bones, which fuse end to end by fibrous connective tissue to form sutures of the cranium (ii) Cartilaginous joints allows only limited movements. Bones are joint together with the help of cartilages. The joint between the adjacent vertebrae in the vertebral column is a cartilaginous joints (iii) Synovial joints are characterized by the presence of fluid filled synovial cavity between the articulating surfaces of the two bones. Such an arrangement allows considerable movement
