The gastric lymph nodes are lymph nodes (also known as lymph glands) which drain the stomach and consist of two sets, superior and inferior: The superior gastric lymph nodes (Latin: lymphoglandulæ gastricæ superiores) accompany the left gastric artery and are divisible into three groups: Upper, on the stem of the artery;
The lymphatic vessels that link the lymph nodes are: The lymphatics of the head, face, neck, and meningeal lymphatic vessels – drain to the deep cervical lymph nodes; The jugular trunk; The subclavian lymph trunk; The thoracic duct; The lymphatics of the upper extremity; The right and left bronchomediastinal lymph trunks; The lymphatics of ...
Lymphatic vessels develop from lymph sacs that arise from developing veins, which are derived from mesoderm. The first lymph sacs to appear are the paired jugular lymph sacs at the junction of the internal jugular and subclavian veins. From the jugular lymph sacs, lymphatic capillary plexuses spread to the thorax, upper limbs, neck, and head.
It carries unfiltered lymph into the node. In doing this they lose all their coats except their endothelial lining, which is continuous with a layer of similar cells lining the lymph paths. Afferent lymphatic vessels are only found in lymph nodes. This is in contrast to efferent lymphatic vessel which are also found in the thymus and spleen.
Lymph enters the convex side of a lymph node through multiple afferent lymphatic vessels, and from there, it flows into a series of sinuses. Upon entering the lymph node, lymph first passes into a space beneath the capsule known as the subcapsular sinus , then moves into the cortical sinuses .
Other lymph nodes in the abdomen are associated with the superior and inferior mesenteric arteries. The celiac lymph nodes are grouped into three sets: the gastric, hepatic and splenic lymph nodes. [citation needed] They receive lymph from the stomach, duodenum, pancreas, spleen, liver, and gall bladder. [1]
Visceral nodes of the abdominal cavity. The hepatic lymph nodes consist of the following groups: (a) hepatic, on the stem of the hepatic artery, and extending upward along the common bile duct, 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;
The ileocolic lymph nodes, from ten to twenty in number, form a chain around the ileocolic artery, but tend to subdivide into two groups, one near the duodenum and the other on the lower part of the trunk of the artery. Where the vessel divides into its terminal branches the chain is broken up into several groups:
