The palatopharyngeal arch (pharyngopalatine arch, posterior pillar of fauces) is larger and projects farther toward the middle line than the anterior; it runs downward, lateralward, and backward to the side of the pharynx, and is formed by the projection of the Pharyngopalatinus, covered by mucous membrane.
