A system of human anatomy, general and special . idal spongy bones in closing the sphenoi-dal sinuses. This portion takes part in the formation of the pterygo-palatine canal. The pterygoid process or tuberosity of the palate bone is the thickand rough process which stands backwards from the angle of union * The perpendicular plate of the palate bone seen upon its external or spheno-maxillarysurface. 1. The rough surface of this plate, which articulates with the superior inaxil-lary bone and bounds the antrum. 2. The posterior palatine canal, completed by thetuberosity of the superior maxillary bone and pterygoid process. The rough surface tothe left of the canal (2) articulates with the internal pterygoid plate. 3 The snhenopalatine notch. 4, 5, 6. The orbital portion of the perpendicular plate 4 The snhenomaxillary facet of this portion; 5, its orbital facet; 6, its maxillary facet to articulatewith the superior maxillary bone. 7. The sphenoidal portion of the perpendicular I he pterygoid process or tuberosity of the VOMER. 85 of the horizontal with the perpendicular portion of the bone. It isreceived into the angular fissure, which exists between the two platesof the pterygoid process at their inferior extremity, and presentsthree surfaces: one concave and smooth, which forms part of thepterygoid fossa ; and one at each side to articulate with the ptery-goid plates. The anterior face of this process is rough, and articu-lates with the superior maxillary bone. Devclopemeni.—By a single centre, which appears in the angle ofunion between the horizontal and perpendicular portion, at the sametime with ossification in the vertebrae. Articulations.—With six bones; two of the cranium, the sphenoidand ethmoid ; and four of the face, the superior maxillary, inferiorturbinated bone, vomer, and the palate bone of the opposite side. Attachment of Muscles.—To four; the tensor palati, azygos uvulae,internal and external pterygoid. Inferior Turbinated Bones.
