angle between the ileum and the csecum, and in the angle between the ileum and 

 the ascending colon. Their afferents are from the posterior part of the caecum 

 and the root of the vermiform process. Their e/erents pass to the main ileo-colic 

 glands.

 considered as forming Main mese nteric glands

four groups, epicolic, 

 paracolic, intermediate, 

 and main. 



The Epicolic Glands 

 are small nodules which 

 lie in the appendices 

 epiploicae and in relation 

 with the wall of the gut. 

 The paracolic glands lie 

 along the medial borders 

 of the ascending, de- 

 scending, and iliac parts Ile - colic art ry 

 of the colon ; along 

 the upper border of 

 the transverse colon, 

 and on the mesenteric 

 border of the pelvic 

 *colon. The intermedi- 

 ate glands lie along the 



branches of the colic

groups are situated 



around the stems from which the colic arteries arise. The lymph gathered by the 

 lymph plexuses in the walls of the gut passes through one or more of the groups 

 of glands, and that which issues from the main group, in association with the 

 ileo-colic and middle colic arteries, enters the main mesenteric glands which 

 surround the upper part of the superior mesenteric artery. It is then carried by 

 the efferent s of those glands to the common intestinal lymphatic trunk. The 

 lymph from the descending, the iliac, and the pelvic parts of the colon passes to 

 the intermediate groups of inferior mesenteric glands and thence, for the main 

 part, to the lumbar glands, but some of the efferents from the upper intermediate 

 inferior mesenteric glands pass to the main group of superior mesenteric glands. 



The lymph glands associated with the middle colic artery and its branches 

 are the lymphoglandulae mesocolicse of the Basle. nomenclature. 



The Main Glands of the Inferior Mesenteric Group receive lymph from the 

 intermediate left colic glands and transmit it to the lumbar glands through which 

 it passes, by the lumbar lymph trunks, to the cisterna chyli; but some of the 

 lymph from the upper intermediate left colic glands passes to the main mesenteric 

 glands, and so to the common intestinal lymph trunk. 



The Middle Supra-pancreatic Lymph Glands of Jamieson and Dobson correspond 

 fairly closely with the lymphoglandulae cceliacae of the Basle terminology. They 

 lie at the upper border of the pancreas around the coeliac artery. Their afferents 

 are from the right and left supra-pancreatic glands, from the posterior left gastric 

 glands, and from the subpyloric glands. They are connected by intermediate 

 channels with the superior mesenteric glands, and they give efferents to the 

 common intestinal lymph trunk and also to the common lumbar trunks. 



Lymphoglandulse Lumbales, B.N.A. The Lumbar Lymph Glands lie behind 

 the peritoneum of the posterior wall of the abdomen, in association with the aorta, 

 the inferior vena cava, the psoas and quadratus lumborum muscles, and the crura 

 of the diaphragm. Those which are situated on the anterior aspect of the aorta 

 are frequently spoken of as pre-aortic glands and those situated more laterally 

 is para-aortic glands. 



The afferents of the lumbar lymph glands are (1) the efferents of the common
