The pharyngopalatine arch (arcus pharyngopalatinus; 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. On either side the two arches are separated below by a triangular interval, in which the palatine tonsil is lodged.
