Verified step by step guidance1
Identify the muscles listed in the problem: Zygomaticus major, Orbicularis oculi, Buccinator, and Masseter.
Understand the function of each muscle: Zygomaticus major is involved in smiling, Orbicularis oculi helps in closing the eyelids, and Buccinator assists in compressing the cheeks.
Recognize that muscles of facial expression are primarily responsible for movements that convey emotions or expressions on the face.
Consider the Masseter muscle, which is primarily involved in mastication (chewing) and not in facial expression.
Conclude that the Masseter is not a muscle of facial expression, as its primary function is related to chewing rather than expressing emotions.
