Joints have been classified on the base of structure and movement. Joints have been divided into three groups on the base of structure.
Joints have been divided into three groups on the base of movement. On a place where bones attach to each other, bones make little movement. But some joints have no moving capacity. Some joints have capacity to move freely. Some joints have slight movement.
