    Study Notes

    Oppositional Movement Terminology

    • Flexion: Reduces the angle between articulating elements in the anterior-posterior plane.
    • Extension: Increases the angle between articulating elements in the same plane.

    Abduction and Adduction

    • Abduction: Movement away from the midline of the body in the frontal plane.
    • Adduction: Movement towards the midline of the body.

    Pronation and Supination

    • Pronation: Rotates the wrist and hand from palm-facing front to palm-facing back.
    • Supination: Rotates the wrist and hand from palm-facing back to palm-facing front.

    Inversion and Eversion

    • Inversion: Twisting motion of the foot that turns the sole inward.
    • Eversion: Twisting motion of the foot that turns the sole outward.

    Plantar Flexion and Dorsiflexion

    • Plantar Flexion: Extends the ankle and elevates the heel, such as when standing on tiptoes.
    • Dorsiflexion: Flexes the ankle and elevates the sole, similar to "digging in heels."

    Protraction and Retraction

    • Protraction: Moves a body part anteriorly in the horizontal plane.
    • Retraction: Moves a body part posteriorly in the horizontal plane.

    Circumduction

    • Circumduction: A type of angular motion involving rotating a joint in a circular manner, such as moving an arm in a loop while drawing a large circle.
