SALIVARY GLANDS OF LOWER PRIMATES 87 



The parotid duct is simple, without lateral derivatives, and with a 

 relatively long buccal submucous terminal segment (5). 



B. INTERMANDIBULAR COMPLEX 



a. Submaxillary Gland 



The submaxillary gland (/) is a globular mass, situated entirely 

 ventrocaudal to the digastric (9) and mylohyoid (/o). The duct is 

 simple and opens by a separate orifice on the medial aspect of the 

 caruncle. 



b. Greater Sublingual Gla)td 



The greater sublingual gland (2) forms a triangular body occupying 

 the anterior parahngual field, covered partially on its lateral aspect 

 by the lesser sublingual glands, but exposed by a deep incisure in the 

 latter's caudal margin, which incompletely divides the lesser sublingual 

 mass into a cephahc and a caudal segment, connected along their oral 

 border by a narrower bridge of gland tissue. The greatei" sublingual 

 duct follows the oral margin of the cephahc lesser sublingual segment, 

 between it and the submaxillary duct, and opens on the parafrenular 

 papilla by a separate orifice. 



c. The Lesser Sublingual Glands 



The distribution of the gland mass (j) is above described, and is 

 typical of the genus, presenting two triangular segments, connected 

 along their oral margins by an intermediate narrower portion, thus 

 allowing the lateral surface of the greater subhngual gland to be 

 seen in the resulting interval from the lateral aspect. The caudal 

 end of the lesser sublingual mass ascends on the lateral aspect of the 

 lingual nerve into the arcus palatinus, and can be traced through the 

 same into continuity with the glands of the soft palate.
