Quizplus · Accepted Answer

The masseter muscle is primarily responsible for actual chewing, as it attaches to the mandible and works to close and retract the jaw during mastication. The buccinator muscle is involved in keeping food between the teeth and cheeks during chewing, but it does not play a direct role in the physical breakdown of food. The zygomaticus muscle is involved in facial expressions and does not contribute to chewing.
