  • How are directional terms typically used in anatomy?
    Directional terms are used in pairs to compare the positions of body parts relative to each other.
  • What is the anatomical position, and why is it important when using directional terms?
    The anatomical position is a standard body posture used as a reference for directional terms, ensuring consistency regardless of the body's actual position.
