- Ball and Socket joints can be found in the hip. These joints allow for movement in many directions.
- Ellipsoid joints can be found in the knee. When the knee is extended, it does not allow rotation. When it is flexed, it allows for limited rotation.
- Saddle joints can be found in the fingers and thumbs.
- Hinge joints can be found in the elbow between the humerus and the ulna. A hinge joint works just like a door hinge, allowing motion in only one direction.
- Pivot joints can also be found in the elbow between the ulna and the radius. This type of joint allows one bone to rotate about the other.
- Gliding joints can be found between the carpals in the wrists. These joints allow limited movement between the bones as one glides past the other.
