The zygomaticus minor is a muscle of facial expression. It originates from M. orbicularis oculi on the lateral face of the zygomatic bone and then inserts on the upper lip. It raises the corners of the mouth and is thus used in smiling. Like all muscles of facial expression, it is innervated by the facial nerve (CN VII).
