92 SALIVARY GLANDS OF LOWER PRIMATES 



sublingual gland (j), in company with the main submaxillary duct, 

 and then follows the dorsal border of the latter to near its termination, 

 where it joins the short common canal (4) produced by union of the 

 main submaxillary (/) and the greater subhngual ducts (2). 



(b) Greater sublingual gland. — A small oval mass, situated between 

 the lesser sublingual glands (j) and the submaxillary duct (i). Its 

 short duct joins the latter a Uttle prior to its union with the secondary 

 submaxillary duct. Main (/) and secondary (i') submaxillary glands 

 and the greater sublingual gland (j) thus open by a single orifice {4) 

 on the pUca sublinguaUs. 



(c) lesser sublingual group (j) extends from near the papilla to the 

 lingual nerve and then ascends along the latter's ventromedial border, 

 intersecting both main and secondary submaxillary ducts at an acute 

 angle.

A. PAROTID is) 



The parotid is a relatively small sub- and preauricular gland, whose 

 duct is simple, without associated elements. It runs a relatively 

 long submucous course, after penetrating the buccinator, to its buccal 

 orifice (5). In this segment it is in relation laterally with a narrow 

 elongated glandular band (7), whose components open independently 

 on the buccal mucosa, without connecting with the parotid duct. 

 The relation of these separate glands, appearing near the termination 

 of the parotid duct, but not connected with the same, to the derivatives 

 of the orbital series and of the orbitoparotid interval is discussed by 

 Schulte in another chapter of this volume (cf. Part V). 



B. IXTERMANDIBULA R COMPLEX 



(a) Submaxillary gland (/) is globular in shape and occupies the 

 usual submandibidar recess. The duct is long and simple. 



ib) The greater sublingual gland (2) forms a narrow mass whose 

 duct unites with the main submaxillary duct just prior to the latter's 

 termination on the papilla {4).
