1 Lateral Flexion â side bending of the axial skeleton. 2  Examples are lateral flexion of the head at the neck and trunk. 3  Abduction and Adduction â frontal plane movements around a sagittal axis occur at multiaxial joints like the bal and socket joint of the shoulder or ellipsoid joints. Abduction and Adduction â frontal plane movements around a sagittal axis occur at multiaxial joints like the bal and socket joint of the shoulder or ellipsoid joints. 2  Abduction is movement away from the midline of the trunk of the body. 3  Adduction is movement medically toward the midline of the body.
