96 OUTLINES OF ANATOMY. 



Superior mesenteric vein, 674-5 ; Fig. 393. (661) 



Tributaries : Right gastro-epiploic. 



Pancreatico-duodenal veins. 

 Lymphatic vessels of the intestines, 703. (687) 



Lymphatics of the small intestine, lacteals. 



Lympathics of the large intestine, (a), (b). 

 Lymphatic glands of the intestines, 703. (687-8) 



Mesenteric glands. 



Meso-colic glands. 



Expose the inferior mesenteric vessels; to do this, draw the small intestine to the right, carefully strip 

 off the peritoneum from the lower portion of the aorta, and to the left, beyond the descending colon and 

 sigmoid flexure. 



Inferior mesenteric artery, 596-7; Fig. 367. (586-7) 

 Branches of the inferior mesenteric : 

 Left colic. 

 Sigmoid artery. 

 (Superior haemorrhoidal.) 

 Chief variations in the inferior mesenteric. 



Inferior mesenteric plexus, 871. (852) 



Aortic plexus, 871. (852) 



Inferior mesenteric vein, 676; Fig. 394. (662) 



Lymphatics of the large intestine, (c), 703. (687) 



Remove the jejunum and ileum from the abdominal cavity. First tie two ligatures around the jejunum 

 at its commencement, and divide the intestine between them; divide the ileum in the same manner, 

 about four inches above its termination in the csecum. Divide the mesentery near the intestine. The 

 portion of intestine thus removed should be washed out and carefully dissected to show the structure. 



Structure of the small intestine, 1003-4-5 ; Figs. 573-4. (982-3) 

 Blood-supply of the small intestine. 

 Lymphatics and nerves. 



Ligature the sigmoid flexure at the brim of the pelvis, and divide the intestine at that point; divide the 

 great omentum along the lower border of the stomach below the gastro-epiploic arteries. Remove the 

 remainder of the ileum and the colon, wash them out, and study the structure. The lower portion of 

 the ileum and the first six inches of the large intestine should be inflated and allowed to dry ; on the 

 dried specimen, remove the lateral wall of the caecum at the point of entrance of the ileum the arrange- 

 ment and structure of the ileo-csecal valve will be shown.

 Blood-vessels. Nerves and lymphatics. 

 The ileo-caecal valve, 1007-8. (986) 



Expose the cceliac axis and its branches; to do this, raise the liver, draw down the stomach, and strip 

 off the anterior layer of the gastro-hepatic omentum. The gastric artery is easily found as it passes 

 along the lesser curvature of the stomach, and by tracing it to its origin the cceliac axis can be readily 

 exposed and its divisions followed.
