The joints which cause rotational movements are
- A. Hinge
- B. Ball and Socket
- C. Cartilage
- D. Sutures
Explanation
A ball and socket joint such as the shoulder or hip allows movement in every plane including rotation, because the rounded head can turn freely within its cup. A hinge joint like the elbow is restricted to one plane and permits no rotation at all. Sutures between the skull bones are immovable and cartilaginous joints allow only slight movement.
