Zygomaticus minor muscle
The zygomaticus minor is a muscle of facial expression. It originates from zygomatic bone and continues with orbicularis oculi on the lateral face of the levator labii superioris and then inserts into the outer part of the upper lip. It draws the upper lip backward, upward, and outward and is used in smiling. Like all muscles of facial expression, it is innervated by the facial nerve (CN VII).
