Joints can be separated into two classes: functional and structural. Joints are divided into three different functional classes. They are synarthroses, amphiarthroses, and diarthroses. Synarthroses means the joint is immovable, amphiarthroses means the joint is slightly moveable, and diarthroses means the joint is freely moveable.
