Visceral lymph nodes | Gastric and Mesenteric

Visceral lymph nodes include Gastric lymph nodes and Mesenteric lymph nodes

Table of Contents

These are (i) ruminal (ii) reticular (iii) omasal and (iv) abomasal nodes.
Three or four glands situated on the right face of the atrium are the atrial nodes.
They receive afferents from spleen, reticulum, rumen and the efferents of the other gastric nodes.
Their efferents unite to form a common efferent, which in turn unites with efferents of the mesenteric nodes to form the mesenteric trunk.
One or two nodes situated in the left longitudinal groove of the rumen are the left ruminal nodes.The efferents go to anterior ruminal nodes.
A number of nodes in the right longitudinal groove of the rumen are the right ruminal nodes. The efferents go to the gastric trunk and anterior ruminal nodes.
A number of nodes situated in the anterior transverse groove are the anterior ruminal nodes. The efferents go to the atrial nodes.
The nodes situated on the reticulo-omasal junction are the reticular glands. Their efferents go to atrial nodes.
Nodes situated along the greater curvature of the omasum are omasal nodes. Their efferent goes to atrial nodes.
Nodes situated along the lesser curvature of omasum and greater curvature of abomasum is abomasal nodes. Their efferents pass to the hepatic nodes.
Nodes situated at the portal fissure of the liver are hepatic nodes. Their efferents go to the gastric trunk.
The pancreatic nodes lie on the inferior face of the pancreas. The efferent joins the intestinal trunk.

The duodenal lymph nodes are in the mesoduodenum and the efferents go to hepatic or abomasal lymph nodes.
Afferents: Efferents of popliteal, superficial inguinal, precrural, abdominal muscles, urinary organs and the vesiculae seminalis.
Efferents: To internal iliac nodes and lumbar trunk.
