    Movement Description ExampleFlexion Angle of joint decreases Bending knee/elbow

    Extension Angle of joint increases Straighteningknee/elbow

    Adduction (ADD) Limb moves closer tomid line of body

    Arm/leg moves towards

    body

    Abduction (TAKE AWAY) Limb moves away frommid line of body Arm/leg moves awayfrom body

    Rotation Limb moves towards midline of the body &changes position of body
