Medial and lateral excursion refer to the side-to-side movement of the mandible during mastication (chewing). This movement is made possible by the action of the lateral pterygoid muscles (one on each side of the jaw), which pull the mandible from side to side. These movements help to grind food between the teeth and prepare it for swallowing.
