The joints which cause rotational movements are

Correct answer: B. Ball and Socket

  • 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.
