Hepatic lymph nodes
Encyclopedia
The hepatic lymph nodes (lymphoglandulæ hepaticæ), consist of the following groups:
The glands of the hepatic chain receive afferents from the stomach
, duodenum
, liver
, gall-bladder, and pancreas
; their efferents join the celiac group of preaortic glands.
- (a) hepatic, on the stem of the hepatic arteryHepatic arteryHepatic artery can refer to:* Common hepatic artery * Hepatic artery proper...
, and extending upward along the common bile ductCommon bile ductThe common bile duct is a tube-like anatomic structure in the human gastrointestinal tract. It is formed by the union of the common hepatic duct and the cystic duct . It is later joined by the pancreatic duct to form the ampulla of Vater...
, between the two layers of the lesser omentum, as far as the porta hepatis; the cystic gland, a member of this group, is placed near the neck of the gall-bladder; - (b) subpyloric, four or five in number, in close relation to the bifurcation of the gastroduodenal arteryGastroduodenal arteryIn anatomy, the gastroduodenal artery is a small blood vessel in the abdomen.It supplies blood directly to the pylorus and proximal part of the duodenum, and indirectly to the pancreatic head .It most commonly arises from the common hepatic artery of the celiac trunk, but there are...
, in the angle between the superior and descending parts of the duodenumDuodenumThe duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms anterior intestine or proximal intestine may be used instead of duodenum...
; an outlying member of this group is sometimes found above the duodenum on the right gastric (pyloric) artery.
The glands of the hepatic chain receive afferents from the stomach
Stomach
The stomach is a muscular, hollow, dilated part of the alimentary canal which functions as an important organ of the digestive tract in some animals, including vertebrates, echinoderms, insects , and molluscs. It is involved in the second phase of digestion, following mastication .The stomach is...
, duodenum
Duodenum
The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms anterior intestine or proximal intestine may be used instead of duodenum...
, liver
Liver
The liver is a vital organ present in vertebrates and some other animals. It has a wide range of functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion...
, gall-bladder, and pancreas
Pancreas
The pancreas is a gland organ in the digestive and endocrine system of vertebrates. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as a digestive organ, secreting pancreatic juice containing digestive enzymes that assist...
; their efferents join the celiac group of preaortic glands.
