30 Bones of the Skull. Crista ettiinoidalis \ Processus orbitalis Maxilla Pars horizontalis Incisura spbenopalatina Processus sphenoidalis Pars perpendicalaris Crista conchalis Facies nasalis Area for completion of the fossa pterygoidea Processus pyramidalis Spina nasalis posterior 37. Right palate bone, os palatinum, from within. The paired os palatinnm (palate bonej (see also Figs. 38, 39, 59, 50, 68—70, 72—74) lies in the pusti-rior part of the nasal cavity and there forms a part of the floor of the same (of the hard palate) and of the lateral wall. It presents for examination a pars horizontalis and a pars perpendiculai'is. The pars horizontalis (0. T. horizontal plate) is very similar to the proc. palatinus maxillae, only shorter; the upper surface (facies nasalis), is smooth and slightly concave; the lower surface (facies palatina), is somewhat rough and presents near the posterior margin a small sickle-shaped elevated surface f.>r the attachment of the m. tensor veli palatini. The anterior, slightly serrated margin lies on the posterior border of the proc. palatinus maxillae and forms with this the sutura palatina transversa. The medial margin unites with the corresponding border of the bone of the other side and forms the posterior part of the siitura palatina mediana; on the upper surface of this border the crista nasalis (for union with the vomer) projects upward and runs out behind into the spina nasalis posterior. The posterior margin is smooth and cuneavi'. From the lateral part of the posterior margin projects baclrsvard the strong processus pyramidalis. It is mserted fi-om in front into the fissura pterygoidea oss. sphenoidalis and helps, with a smooth area on its posterior surface, to complete the inferior part of the fossa pterygoidea. The external, rough sui-face unites with the posterior portion of the corpus maxillae just above the eighth alveolus. The medial, smooth surface looks into the nasal cavity. The inferior surface belongs to the lower surfiiee of the hard palate and contains usually throe openings, of which the foramen palatinum majus lies furthest forward, the others, foramina palatina tninora, lie further baclvward. These are the outlets of the canales palatini (for the aa. palatinae major et minores: nn. iialatinil which sotiietimos mien lnt-,.rnl-
Processus orbitalis luciaura spheuopalatina Processus sphenoidalis Crista conchalis Crista nasalis Fades nasalis " Spina nasalis posterior Bones of the Skull. 31 Sulcus pterygopalatinus Area completing the fossa pterygoidea Pars perpendicalaris I Pars horizontalis Processus pyramidalis ' Processus Processus sphenoidalis j ; Incisina spheuopalatina pyramidalis Processus orbitalis l-'acies maxlllaris Sulcus pterygopalatinus ; Foramen palatinum majus Area completing the fossa pterygoidea 38 and 39. Right palate bone, os palatinum. From behind. From M'ithout. The pars perpendicnlarig (0. T. vertical plate) ascends as a thin leaf of bone verti- cally upward fi-om the lateral margin of the pars horizontalis. The medial fades nasalis is smooth and presents two ridges extending from before backward, an upper, shorter, crista ethmoidalis (0. T. superior turbinated crest), for the attachment of the concha nasalis media, and a lower, crista conchalis (0. T. inferior turbinated crest), for union with the concha nasalis inferior. The lateral surface, fades maxillaris, is for the most part rough and unites with the posterior, rough portion of the fades nasalis corporis maxiUae, so that it covers over a portion of the hiatus maxillaris from behind; it is attached behind to the anterior margin and the medial surface of the lamina medialis pr(jc. pterygoidei oss. sphenoidalis. Between these two areas, extending from above downwards, is the smooth, shallow sulcus pterygopalatinus. Through the attachment of the fades maxillaris to the two bones mentioned this forms together with the sulcus pterygopalat. of the proc. pteryg. oss. sphenoidalis and a groove on the upper jaw bone, above, the fossa pterygopalatina , open lateralward (for the aa. maxill. int., palat. descendens, sphenopalat. ; nn. zygomat., sphenopalat., alveol. sup., infraorbit. ; gangl. sphenopalat.) , below, the canalis pterygopalatinus (0. T. posterior palatine canal) (for the a. palat. descendens; nn. palat., rr. nasal, post. inf. gangl. sphenopalat.), closed also externally by the proc. pterygoideus oss. sphenoid, and the upper jaw; it is continued below into the canales palatini (for the aa. palatinae major et minores ; nn. palat.) which usually run in the proc. pyramidahs alone. Prom the upper margin of the pars perpendicularis extend two processes, the processus sphenoidalis bent somewhat backward and markedly medianward, which lies on the inferior surface of the body of the sphenoid and on the ala vomeris, and the processus orbitalis forward and somewhat lateralward. The latter is bulged out and contains a small cavity whicli helps to close the posterior ethmoidal cells. Its lateral, smooth surface forms the most posterior part of the floor of the orbit ; in front and below it meets the fades orbitalis corporis maxillae (sutura palatomaxillaris), in front and above the lamina papyracea oss. ethmoid, (sutura palatoeihmoidalis) , behind and above the anterior margin of the latn-al surface of the body of the sphenoid (sutura sphenoorhitalis) ; behind and below it lies free and helps in part to form the medial portion of the fissura orbitalis inferior, in part it looks
