of till' palate hoiu'. The extreme posterior border receives the tuberosity of the 

 ])alate hone; the grocjve in front of it forms jxirt of the ])osterior palatine canal. 

 .Vnterior to this surface the hone l)ecomes suddenly smooth; Ijetween the smooth 

 and roujzh portions is the maxillary fissure for the reception of the thin maxillary 

 process on the anterior border of the vertieal plate of the palate bone. In the 

 antrle between this surface and the nasal process is a deep groove converted by the 

 laehrvmal and inferior turV)inal into the nasal duct. Running liackwards from

the anterior margin is the inferior turbinated crest which articulates with the 

 lowest turbinal bone. The surface above the crest forms part of the middle 

 nieatus, and the surface below belongs to the inferior meatus of the nose, and is 

 directly continuous with the superior surface of the i)alatine process. Near its 

 anterior border is the orifice of the anterior palatine canal. 



The inferior or palatine surface is formed by the palatine process and the 

 alveolar liorder. The palatine process forms the anterior part of the roof of the

inouth. It is concave, rough, and pitted with foramina for vessels. Where it 

 joins the alveolar border a groove (sometimes a canal) exists for the anterit)r 

 palatine nerve and ])osterior palatine vessels. When the bones of opposite sides 

 are placed in apposition the palatine fossa is formed; running outwards from this 

 to the space between the second incisor and canine tooth, the maxillo-premaxillary 

 suture can be detected in young bones. Tlie posterior border articulates with the 

 horizontal process of the palate bone, whilst the median border joins its fellow to 

 form above, a ]irominent crest upon which the vcMuer is received.
