Gastric lymph nodes
Encyclopedia
The gastric lymph nodes consist of two sets, superior and inferior.
- The Superior Gastric Glands (lymphoglandulæ gastricæ superiores) accompany the left gastric arteryLeft gastric arteryIn human anatomy, the left gastric artery arises from the celiac artery, and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus...
and are divisible into three groups, viz.:- (a) upper, on the stem of the artery;
- (b) lower, accompanying the descending branches of the artery along the cardiac half of the lesser curvature of the stomachLesser curvature of the stomachThe lesser curvature of the stomach, extending between the cardiac and pyloric orifices, forms the right or posterior border of the stomach.It descends as a continuation of the right margin of the esophagus in front of the fibers of the right crus of the diaphragm, and then, turning to the right,...
, between the two layers of the lesser omentumLesser omentumThe lesser omentum is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum.- Structure :...
; - c) paracardial outlying members of the gastric glands, disposed in a manner comparable to a chain of beads around the neck of the stomach. They receive their afferents from the stomach; their efferents pass to the celiac group of preaortic glands.
- The Inferior Gastric Glands (lymphoglandulæ gastricæ inferiores; right gastroepiploic gland), four to seven in number, lie between the two layers of the greater omentumGreater omentumThe greater omentum is a large fold of parietal peritoneum that hangs down from the stomach...
along the pyloric half of the greater curvature of the stomachGreater curvature of the stomachThe greater curvature of the stomach is directed mainly forward, and is four or five times as long as the lesser curvature.-Surface:Starting from the cardiac orifice at the incisura cardiaca, it forms an arch backward, upward, and to the left; the highest point of the convexity is on a level with...
