DIGESTIVE SYSTEM OF THE PIG 



The parotid gland is large and triradiate. It extends very little on to the mas- 

 seter muscle and its upper angle does not quite reach the base of the ear. It is 

 pale in color and is embedded in fat in animals in good condition. On its deep 

 face are several large subparotid lymph glands, some of which are only partially

covered by the parotid. The duct arises on the deep face, has a course similar 

 to that of the ox, and perforates the cheek opposite the fourth or fifth upper cheek 

 tooth. Small accessory glands (Glandule parotides accessorial) may be found 

 along the course of the duct.
