1. The pivot joint: Spinning around a single axis of rotation, it has one degree of freedom an example is proximal radial ulnar joint and the atlantoaxial C1 and C2.
2. The hinge joint: It has one plane of movement which is flexion and extension. An example of the hinge joint would be the elbow joint or the interphalangeal joints.
3. The ellipsoid joint: Ithas two plane of freedom which is flexion/extension and abduction/adduction, it restricts spin. An example of this would be wrist.
4. Ball and socket joint: This is the most versatile joint and has three planes of movement. Flexion/extension, abduction/adduction, and external/internal rotation. An example would be the shoulder or the hip.
5. Condyloid joint: Has three planes of movement. Flexion/extension, abduction/adduction or flexion/extension and rotation. An example of this would metacarpalphalangeal (knuckles), the knee and the atlanto-occipital joint. Joint meets at a concave fashion.
6. Plane joint: It has two degrees of freedom. Movement combines some sliding and some rotation of one partner with respect to another. An example of this joint is: wrist bones, rotation and translation, ligaments in the hand restrict the movement of the hand.
7. Saddle joint: There are two degrees of movement. Flexion/extension and adduction/abduction. Both bones are built with convex and concave. An example would be: Carpalmetacarpal of the thumb.
