A. PAROTID 



The main portion of the gland, nearly quadrangular in shape (5), is 

 composed of small, closely packed lobules, and occupies a submeatal 

 position, covering the masseter, and extending into the retromandib- 

 ular region over the sternomastoid. In addition to this main gland, 

 and only separated from the same by the masseteric branch of the 

 facial vein, an extensive socia parotidis (6), composed of larger and 

 more loosely connected lobules, envelops Stenson's duct between the 

 point of its emergence from the ventral margin of the main gland and 

 its engagement in the buccinator, so that only the short intramural 

 segment of the duct is free from glandular investment. The associ- 

 ated parotid lobules enter the main parotid canal by a smaller dorsal 

 and larger ventral duct, directed forward towards the intramural seg- 

 ment. There is no retroauricular extension of the main gland. 



B. INTERMANDIBULAR COMPLEX 



The three t^-pical glands of this region are present and well 

 developed. 



ia) Submaxillary gland (/). — The gland is simple, consisting of a 

 single oval mass situated entirely below the mylohyoid in the sub- 

 mandibular fossa, deeply grooved on its ental surface by the submax- 

 illary vascular trunks. The hilus occupies nearly the center of the 

 ventromedial surface. Wharton's duct passes as a single canal with- 

 out lateral derivatives in the classical course to its separate terminal 

 orifice (/) on the plica sublingualis, mesal and cephalal to the remain- 

 ing glands in the floor of the mouth (Fig. i, /). 



(b) The greater sublingual gland (2). — This gland appears as a well- 

 defined almond-shaped body, lying below and behind the main portion
