Mesenteric lymph nodes
The mesenteric lymph nodes ( Nodi lymphatici [Nll.] Mesenterici or Lymphonodi [Lnn.] Mesenterici ) are lymph nodes of the abdominal cavity that lie directly on the aorta . A distinction is made between two groups of lymph nodes: The upper mesenteric lymph nodes Nll. mesenterici superiores (in animal anatomy referred to as the anterior mesenteric lymph nodes, Lnn. mesenterici craniales ) at the origin of the arteria mesenterica superior and the lower mesenteric lymph nodes Nll. mesenterici inferiores (referred to in animal anatomy as the posterior mesenteric lymph nodes, Lnn. mesenterici caudales ) at the origin of the arteria mesenterica inferior .
In a broader sense, the term includes all lymph nodes located in the mesenteries of the abdominal cavity. In humans, around 200 and thus around a third of all lymph nodes are in the mesentery. In veterinary anatomy, these lymph nodes are grouped into two lymphatic centers ( Lymphocentrum mesentericum craniale and Lc. Mesentericum caudale ).
