Lateral movement away from the midline of the body; moving the head toward the shoulder (left or right) at a joint below the skull.
- See muscles responsible for Rotation
Return to the anatomical position from lateral movement; moving the head upright away from the shoulder at a joint below the skull.
- See muscles responsible for Rotation

Rotary movement around the longitudinal axis of the bone; turning the head to the side (right or left) at a joint below the skull.
