    abduction
  35. It is moving the bone or limb toward the midline of the body
    Adduction
  36. It is the act of moving the bone around a central axis
    Rotation
  37. Is moving the bone in such a way that the end of the bone or a limb describes a circle in the air and the sides of the bone describe a cone in the air
    Circumduction
  38. They refer to the movement of the forearm and the hand
    Supination and Pronation
  39. It is moving the bone so that the radius and the ulna are parallel
    Supination
  40. It is moving the bones of the forearm so that the radius and ulna are not parallel
