The '''Zygomatic major''' is a [[muscle]] of the [[human body]]. It is a [[muscle of facial expression]] which draws the angle of the mouth superiorly and posteriorly. Like all muscles of facial expression, the zygomatic major is innervated by the [[facial nerve]] (Cranial Nerve VII).
The Zygomaticus extends from each zygomatic arch ([[cheekbone]]) to the corners of the mouth. It raises the corners of the mouth when a person smiles.
