98 OUTLINES OF ANATOMY. 



Duodenum, 1000-1-2; Figs. 570-1. (978-9-80-1) 



First part, the superior or ascending. 



Second part, the descending portion. 



Third part, or transverse portion. 



Fourth part. Musculus suspensorius duodeni. 



Pancreas, 1023-4-5 ; Fig. 587. (1001-2) 

 Head of the pancreas. 

 Body of the pancreas. 

 Tail of the pancreas. 



Open the gland by an incision a little below the median line, extending from the head to the tail, 

 and expose the duct. 



Duct of the pancreas. 



Blood-supply. Lymphatics. Nerves. 

 The common bile duct, ampulla of Vater, 1021. (999) 

 Abdominal branches of the pneumogastric nerve, 819. (800) 



Apply a ligature and divide the resophagus just below the diaphragm. Remove the stomach, duo- 

 denum, pancreas, and spleen, dividing the vessels and folds of peritoneum which hold them in place. 

 The arteries should be divided about an inch from their origin. Divide the pancreatic duct near the 

 duodenum, remove the gland, and examine its structure. Clean the surface, and wash out the duo- 

 denum and stomach, and study their structure. 



The pancreas, 1023-4-5. (1001-2) 



Lymphatics of the pancreas, 704. (689) 

 The stomach, 998-9; Figs. 568-9. (977-8)- 



Structure. 



Nerves. Blood-supply. Lymphatics. 

 The pylorus, 996; Fig. 566. (974-5) 

 Duodenum-Structure of small intestine, 1003-4. (982-3) 

 The spleen. 



Structure. Blood-supply. Lymphatics. Nerves, 1028. (1005-6) 



Lymphatics of the spleen, 704. (689) 

 Splenic glands. 



Remove the liver and demonstrate its parts and structure. To remove the liver, cut the hepatic artery 

 near its origin; divide the suspensory ligament from before backward, drawing the liver downward 

 and forward ; divide the lateral ligaments and the upper layer of the coronary ligament, separate the 

 posterior border of the liver from the diaphragm, and divide the inferior layer of the coronary ligament. 

 Divide the vena cava just above the posterior border, and again, just below it. Cut the ligaments close 

 to the abdominal wall, so that their connection with the liver can be studied when the organ is 

 removed. 



The liver. 



Relation to the peritoneum, 1018-19. (996-7) 

 Ligaments of the liver, 1019. (997) 



Coronary ligaments.

Broad ligament. 



Round ligament. 



Carefully expose the fissures and demonstrate the vessels, ducts, etc., entering or emerging from 

 the liver.

Structure of the gall bladder.
