The story of the word

Greek physicians named the muscle for its only job, from μασᾶσθαι, to chew, the verb also behind mastic and masticate. For its size it is among the strongest muscles in the body, which is why it is the one that aches after a night of grinding teeth. Clench your jaw with a hand on the cheek and you can feel it stand out under the fingers.
