THE BONY FRAMEWORK 



higher cheek bones than others. Indeed, some races, like 

 the American Indians, are recognized by the peculiarity 

 in the size and shape of their cheek bones. 



The two nasal bones form the hard part, or bridge, of 

 the nose. 



The two upper jawbones form a part of the roof of the 

 mouth and the floors of the orbits. In them is fixed the 

 upper set of teeth. 



The lower set of 

 teeth is fixed in 

 the lower jawbone, 

 which moves by 

 means of a hinge 

 joint, thus allowing 

 the opening and 

 shutting of the 

 mouth. 



35. The Smaller 

 Bones of the Face. 

 The remaining 

 bones of the face 

 are small. Two 

 bones, forming the 

 back part of the 

 roof of the mouth, 

 are called the palate bones. Sometimes infants are born 

 with a "cleft palate." This means that the two palate 

 bones have not been joined together. 



Two little bones, made like little troughs, carry the tears 

 from the eyes to the nose. They are in shape somewhat 

 like the finger nails, and are called the lachrymal bones, 

 from a Latin word meaning tear.
