ELEMENTS OF MAMMALIAN ANATOMY. 



craniad of the submaxillary. Its duct extends parallel with 

 that of the submaxillary and opens within the mouth upon 

 the same papilla beneath the tongue. The molar gland is 



very small and lies near the 

 angle of the mouth ventrad 

 of Stenson's duct. Its sev- 

 eral ducts, which are not 

 easily demonstrated, pass 

 through the cheek to open 

 within the mouth. The zy- 

 gomatic or infraorbital gland 

 lies on the lateral part of the 

 orbit on the ventro-lateral 

 surface of the eyeball. It 

 may be seen by cutting away 

 the zygomatic arch and the 

 masseter muscle. From near 

 the ventral angle of the gland 

 a duct leads to the roof of the mouth posterior to the molar 

 tooth. 



The liver is the largest gland in the body and is situated 

 immediately caudad of the diaphragm (Fig. 55), and in 

 contact with the right lateral and cranial surfaces of the 

 stomach. It is strongly convex on its cranial aspect while 

 its opposite surface presents a deep concavity occupied by 

 the stomach. Several deep incisions named fissures divide 

 the liver into five parts called lobes. The falciform or 

 suspensory ligament which is a fold of peritoneum joins the 

 liver to the diaphragm and extends into the large median 

 fissure known as the umbilical notch because during fetal 

 life it shelters the vein leading through the umbilical cord 

 to receive nourishment from the mother. 



On the right side of the body from the umbilical notch 

 is the large right median lobe enfolding the gall bladder.
