PALATE BONES, (oSSA PALATI.) 
Situation, —Infero-posteiior part of the face, adjoining the 
base of the cranium. 
Figure ,—One portion is semi-circular ; otherwise it is irregular. 
Surfaces. —The palatine surface is that which is turned 
downwards, and contributes to the formation of the palatine arch. 
The nasal surface^ the broadest, confronts its fellow, the two 
forming the sides of the posterior opening of the nose : its supero- 
posterior part is pierced by the posterior palatine foramen. The 
orbital surface is in part smooth, where it enters into the compo¬ 
sition of the back of the orbit; and in part rough and laminated, 
where it articulates into the superior maxillary bone: the latter 
portion exhibits the palatine canal, which leads to the anterior pala¬ 
tine foramen. Between this and the superior maxillary bone a 
hiatus, or sort of vestibule, is left vacant, in which is observable the 
posterior opening of the foramen above-mentioned, besides two 
others formally described. The ethmoidal surface is divided from 
the nasal by the palatine crest, to which the vomer is joined: it is 
oblong and concave, and constitutes the floor of the ethmoidal 
sinus, possessing several irregular ridges, which form so many im¬ 
perfect septa, projecting into the cavity. 
Borders. —The palatine, round, smooth and lunated, forms 
the circumferent boundary-line of the posterior opening of the 
nose, and affords attachment to the velum palati: from it, poste¬ 
riorly, descends the styloid process, whose extremity, in the recent 
subject, is provided with a cartilaginous pulley, in which runs the 
tensor palati; the posterior side of the process is rough and lanii- 
nated for articulation with the pterygoid process of the sphenoid 
bone. The supero-lateral and infero-lateral borders unite with
