(I) Fibrous joints or Synarthroses: They are immovable fixed joints in which no movement between the bones is possible. Sutures of the flat skull bones are fibrous joints.
(II) Cartilaginous joints or Amphiarthroses: They are slightly movable joints in which the joint surfaces are separated by a cartilage and slight movement is only possible, e.g., Joints of adjacent vertebrae of the vertebral column.
(III) Synovial joints or Diarthroses joints: They are freely movable joints, the articulating bones are separated by a cavity which is filled with synovial fluid e.g., Pivot joint – between atlas and axis plane/gliding joint – between the carpals
- Saddle j oint – between the carpal and metacarpal
- Ball and socket joint – between humerus and pectoral girdle
- Hinge joint – knee joint
- Condyloid or angular or ellipsoid-joint between radius and carpal.
