Relations. 



Note carefully the relations of the pancreas to the lumbar ver- 

 tebrae, the stomach, the left kidney, the spleen, the superior 

 mesenteric vessels, the splenic vessels, the inferior mesenteric 

 vein, the ligamentum pancreaticolienale, and the duodenum. 

 What are " fasciae of fusion," and what relation has the pancreas 

 to such? (Vide Figs. 263, A and B.) Dissect away some of the 

 parenchyma of the gland and determine, if possible, the source 

 and relations of the pancreatic ducts : 1
