[Chap. IV. 



The inferior turbinated bones are situated on the outer wall 

 of each side of the nostril. Each consists of a layer of thin,

spongy bone, curled upon itself like a scroll ; hence its name, 



"turbinated." 



The superior maxillary is one of the most important bones 



of the face, in a surgical point of 

 view, on account of the number of 

 diseases to which some of its parts 

 are liable. With its fellow of the 

 opposite side, it forms the whole of 

 the upper jaw. Each bone assists 



in forming part of the floor of the orbit, the floor and outer 



wall of the nasal fossoe, 



and the greater part of the 



roof of the mouth. That 



part of the bone which con- 

 tains the teeth is called the 



alveolar process, and is exca- 



vat€id into cavities, varying 



in depth and size according 



to the size of the teeth they 



contain. There are eight 



cavities in each bone: those 



for the canine teeth are 



the deepest ; those for the 



molars are widest and sub- 

 divided into minor cavities; 



those for the incisors are 



single, but deep and narrow.
