the nerves conveying the sense of smell pass. Descending 

 from this perforated plate, on either side of the nasal cavity, 

 are two masses of very thin, spongy, bony tissue. 

 Bones of the face : 



Nasal 2 



Lachrymal 2 



Vonier 1 



Malar 2 



Palate 2 



Inferior turbinated 2 



Superior maxillary 2 



Inferior maxillary 1

The nasal bones are two small oblong bones, 



varying in size and form in different individ- 

 uals; they are placed side by 

 side at the middle and upper 

 part of the face, forming by their 

 junction "the bridge" of the 

 nose. 



The lachrymal are the smallest 

 and most fragile bones of the 

 face. They are situated at the 

 front part of the inner wall of the orbit, and 



resemble somewhat in form, thinness, and size, a finger-nail. 

 The vomer is a single bone 



placed at the back part of 



the nasal cavity, and forms 



part of the septum of the 



nasal fossse. It is thin, 



and shaped somewhat like a 



ploughshare, but varies in 



different individuals, being 



frequently bent to one or 



the other side. 



The malar or cheek bones form the prominence of the cheek, 



and part of the outer wall and floor of the orbit. 



The palate bones form (1) the back part of the roof of the 



mouth ; (2) part of the floor and outer wall of the nasal fossae; 



and (3) a very small portion of the floor of the orbit.
