Which muscle raises the corner of the mouth?

Explanation:
When you lift the corner of the mouth, the muscle at work is the levator anguli oris. It starts near the upper jaw and attaches at the angle of the mouth, so its contraction pulls the corner upward. This action helps form a smile and pairs with other muscles like the zygomaticus major for a fuller expression. The levator labii superioris mainly raises the upper lip, not the corner; the depressor labii inferioris pulls the corner downward; and the nasalis controls the nose rather than the mouth. So the muscle that raises the corner of the mouth is levator anguli oris.
