and left lateral borders forms a prolongation, termed the processus uncinatus. 

 In the groove between the duodenum and the right lateral and lower borders 

 in front are the anastomosing superior and inferior pancreaticoduodenal arteries; 

 the common bile duct descends behind, along the right border, to its termination 

 in the second part of the duodenum.

The greater part of the right half of the anterior surface is in contact with the 

 transverse colon, only areolar tissue intervening. From its upper part the neck 

 originates, its right limit being marked by a groove for the gastroduodenal artery. 

 The lower part of the right half, below the transverse colon, is covered by peri- 

 toneum continuous with the inferior layer of the transverse mesocolon, and is 

 in contact with the coils of the small 

 intestine. The superior mesenteric artery 

 passes down in front of the left half 

 across the uncinate process; the superior 

 mesenteric vein runs upward along the 

 right side of the artery, and, behind the 

 neck of the pancreas, joins with the 

 splenic vein to form the portal vein. 



The posterior surface is in relation with 

 the inferior vena cava, the renal veins, 

 the right cms of the Diaphragm, and 

 the aorta. 



The neck springs from the right upper 

 portion of the front of the head. It is 

 about an inch (2.5 cm.) long, and is 

 directed, at first, upward and forward, 

 and then upward and to the left to join the body; it is somewhat flattened 

 from above downward and backward. Its antero-superior surface supports the 

 pylorus; its postero-inferior surface is in relation with the commencement of the 

 oortal vein; on the right it is grooved by the gastroduodenal artery.
