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.
