PRIMATE ALVEOLINGUAL SALIVARY AREA

secreting gland and 

 conducting canal is 

 largely governed by 

 the mechanical lim- 

 its of the supramylo- 

 hyoid oral floor. 



Cephalad of the 

 lingual nerve inter- 

 section the available 

 developmental field 

 is ample, aft'ording 

 the opportunity for 

 multiple separate 

 glandular develop- 

 ment, as well as for 

 the production of 

 the ducts of the 

 more specialized in- 

 dividual glands. 

 Caudad of the lin- 

 gual nerve intersec- 

 tion the genetically 

 available space di- 

 minishes as the 

 faucioUngual isth- 

 mus is approached. 

 This potentially re- 

 duced area between 

 the Ungual nerve 

 and the anterior 

 faucial pillar is ap- 

 parently bridged in 

 two ways : —
