Joints that allow for expansion and contraction but not free moving (slightly movable) ( pubis symphysis)
Synarthrodial joints
Completely fused, non moving joints ( skull sutures)
Hinge joint
Flexion and extension only ( the elbow)

Condyloid joint
Flexion, extension, abduction, adduction
Ball & socket joint

Pivot joint
