Answer: C - Flexion is bending a joint or decreasing the angle between two bones.
15. Moving a body part away from the midline is called:
  • A) Adduction
  • B) Abduction
  • C) Retraction
  • D) Pronation
Answer: B - Abduction is moving a body part away from the midline of the body.
16. Pronation of the forearm involves:
  • A) Turning the palm upward
  • B) Turning the palm downward
  • C) Moving the arm toward the midline
  • D) Bending the elbow
Answer: B - Pronation is turning the arm or foot downward (palm or sole of the foot facing down).
17. Which ankle movement points the foot downward (like a ballet dancer on tiptoe)?
  • A) Dorsiflexion
