Which term is used to describe the action of moving a joint around its axis?

Explanation:
Rotation names the action of turning a joint around its long axis. This movement involves spinning the body part so it faces a different direction, with the axis running through the joint itself. You can think of turning your head from side to side or rotating the forearm so the palm faces up or down. Rotation can be internal (toward the midline) or external (away from the midline). Other terms like rights, role, or safety don’t describe how joints move, so rotation is the precise word for this action.
