490 LABORATORY MANUAL OF HUMAN ANATOMY 



(bd) Lienal or splenic vein (V. lienalis). 



(bda) Short gastric veins (Vv. gastricae breves}. 



(bdb) Left gastro-epiploic vein (V. gastro-epiploica sin- 



istra). 



(bdc) Cystic vein (V. cystica}. 



(be) Parumbilical veins (Vv. parumbilicales [Sappeyi]). 



What are the following anastomoses in the domain of the V. 

 portae ? 



(1) Oesophageal anastomosis. 



(2) Rectal anastomosis. 



(3) Peritoneal anastomosis (veins or system of Retzius). 



(4) Umbilical anastomosis (veins of Sappey). What is the 



" caput medusae," sometimes met with when the V. portae 

 is obstructed in the liver? 

 Are any of the accessory portal veins present? 



(1) Deep cystic veins, passing from the fossa vesicae felleae and 



the non-peritoneal surface of the gall-bladder directly into 

 the liver. 



(2) Epiploic veins, passing from the omentum minus and the 



hepatocolic and hepatorenal ligaments. 



(3) Veins of the hilus. 



(4) Veins from the diaphragm, which pass through the coronary 



ligament of the liver. 



(5) Veins of the ligamentum falciforme hepatis. 



(c) Hepatic artery (A. hepatica). (Vide Spalteholz, Fig. 464.) 



(ca) Right gastric artery (A. gastrica dextra). 



(cb) Proper hepatic artery (A. hepatica propria). 



(cba) Right branch (ramus dexter}, 

 (ebb) Cystic artery (A. cystica). 

 (cbc) Left branch (ramus sinister). 



(cc) Gastroduodenal artery (A. gastroduodenalis) . 



(cca) Superior pancreaticoduodenal artery (A. pancreati- 



coduodenalis superior). 



(1) Pancreatic branches (rami pancreatici) . 



(2) Duodenal branches (rami duodenales). 



(ccb) Right gastro-epiploic artery (A. gastro-epiploica 



dextra). 



(1) Epiploie branches (rami epiploici). 



Later this artery (right gastro-epiploic) will be 

 traced back to its origin, the coeliac artery (A. 

 coeliaca). Pay especial attention to the relations of 

 the hepatic artery to the ductus choledochus and 

 vena portae. What anomalies of the hepatic artery 

 frequently occur? 



(d) Hepatic plexus of sympathetic nerves (plexus hepaticus). 



The filaments of this plexus will be found accompanying the 

 arteria hepatiea propria and each of its branches. Dissect these 

 filaments out and study their distribution. 



(e) Lymph-glands. 



What is the exact position of the cystic lymph-glands (lympho- 

 glandulae cysticae} and the lymph-gland of the portal vein
