Etymology

In English, this muscle’s name means the trumpeter muscle. Buccinator comes from the Latin word buccina meaning a “trumpet or shepherd’s horn.” This instrument received its name because the bucca, Latin meaning “cheek,” was used to blow into it. Therefore, buccinator means “the trumpeter.”

Insertion

Action

Tense the cheeks to help move food between the molar teeth when chewing and help keep the cheek mucosa from getting pinched between the grinding surfaces of the teeth. When air is trapped in the mouth, they help expel the air, as in blowing air from the mouth.

Facial nerve (Cranial nerve VII)
