Joints

Joints, also known as articulations, are a form of connection between bones. They provide stability to the skeletal system as well as allowing for specialized movement.

Gross anatomy

Joints can be classified into three broad types according to the tissue that binds them.

Structural types

• fibrous joints 
• cartilaginous joints
• synovial joints

Functional types

• synarthroses: allow very little, if any, movement
• amphiarthroses: allow a small amount of movement
• diarthroses: freely moving
