Extension

Moving parts at a joint so that the angle between them increases and the parts move farther apart

Extension

Straightening the knee

Hyperextension

Lateral Roation

Turning of a limb on its longitudinal axis in the opposite direction

Lateral Rotation

Bending the arm and moving it away from the body

Medial Rotation

Turning of a limb on its longitudinal axis so its anterior surface moves toward the midline

Medial Rotation

Bending the arm and moving the arm toward the body

Circumduction

Moving a part so that its end follows a circular path

Circumduction

Moving the finger in a circular motion without moving the hand

Adduction

Moving a part toward the midline or toward the axial line of the limb (moving fingers and toes cloer together)

Adduction

Returning the upper limb from the horizontal position to the side of the body

Abduction

Moving a part away from the midline or away from the axial line of the limb (spreading fingers or toes)

Abduction

Lifting upper limb horizontally to form an angle with the side of the body

Dorsiflexion

Inversion

Walking on the outsides of one’s feet

Eversion
