[TA]
facial muscle of cheek; origin, posterior portion of alveolar portion of maxilla and mandible and pterygomandibular raphe; insertion, angle of mouth; also become interspersed with more horizontal portions of the orbicularis oris; action, flattens cheek, retracts angle of mouth; plays an important role in mastication, working with tongue and orbicularis oris muscle to keep food between teeth; when it is paralyzed, as in Bell palsy, food accumulates in the oral vestibule; nerve supply, facial.

Etymology: L, buccina, trumpet
the main muscle of the cheek, one of the 12 muscles of the mouth. It is pierced by the duct of the parotid gland opposite the second molar tooth. The buccinator, innervated by buccal branches of the facial nerve, compresses the cheek, acting as an important accessory muscle of mastication by holding food under the teeth.
