Final Answer :
True
Explanation :
Medial and lateral excursion are specific movements of the mandible, which is the only movable bone in the skull that forms the lower jaw and is responsible for chewing, biting, and speaking. Medial excursion refers to the jaw's movement inward or toward the midline, and lateral excursion refers to the movement outward or away from the midline. These motions are controlled by the temporalis, masseter, medial and lateral pterygoid muscles, which attach to the mandible and allow it to move in different directions.
