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 sy- 
gomatic or infraorbital gland

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 wmbilical 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.
