THE ANATOMY OF THE ADULT HUMAN SALIVARY GLANDS II 



designated them in the figures. The most cephalic member of the 

 group was described (1722) by Nuck in the dog, and is hence some- 

 times called the Glandula Nuckii. The little series of glands was 

 also recognized by Ward, who described them under the name of 

 "molar glands" in Todd's "Encyclopedia of Anatomy and Physi- 

 ology" (Vol. I\', Part I, p. 426). 



[For the details of the adult anatomy of these structures in the carnivora, see 

 Carmalt's account and illustrations in Part V ; the ontogeny of the structures 

 in carnivora and their relation to the orbital inclusion is treated by Schulte in 

 extenso in Part VI.] 



One of the best examples of the full development of the orbital 

 series which I have encountered in the series of adult human subjects 

 examined is shown in Fig. 9. 



Caudomesad of the terminal segment of the parotid duct a series 

 of six little spherical glands extends dorsad along the buccinator 

 muscle into the entomassetcric recess. These are the orbital glands 

 (7). A few scattered glandular nodules lie just cephalad of the parotid 

 duct terminal. They are separated by a short interval from a more 

 extensive series of superior alveobuccal glands (8), to which group 

 I believe they belong genetically. 



Figure 12 shows this same preparation from in front and below,' 

 opening up a view into the deep entomasseteric fossa and emphasiz- 

 ing the divergent course of the orbital series (7) and the parotid duct 

 in reference to the two surfaces of the masseter muscle. The latter 

 has been divided at the cephalic border of the parotid and the cephalic 

 segment, together, with mandible and internal pterygoid, have been 

 removed, in order to expose the orbital glandular row. In the intact 

 condition of the masseter the orbital glands lie on the mesal surface 

 of the muscle, separated by the same from the parotid duct. 



Figure 7 shows the same group of separate and distinct glandular 

 masses of the orbital series (7) caudomcsal to the main parotid duct 

 terminal, extending from the latter's buccal orifice mesal to the masseter 

 muscle.
