Where do the back fibers of the buccinator originate?
Some of the back fibers of posterior origin attach to the buccinator crest, the small ridge on the retromolar triangle (anterior, horizontal portion of retromolar fossa). Additionally, some fibers of the buccinator arise from the pterygomaxillary raphe, a fibrous band that extends from the pterygoid hamulus to maxillary tuberosity.
