Macro-and microanatomy lymph nodes small intestine Orenburg goat breed

Regional lymph nodes of the small intestine of Orenburg goat breeds are lymph nodes of the duodenum, jejunum and ileum. Lymph nodes of the duodenum include duodenal-pancreatic, liver (portal) lymph nodes visceral surface of the liver, dorsal pyloric abomasum and cranial mesenteric lymph nodes jejunum.Regional lymph nodes jejunal mesenteric lymph nodes are a group located in a row between the barrel of the cranial mesenteric artery (vein), and jejunum. These include cranial, middle, and caudal mesenteric lymph node groups.Podvzdoshnoobodochnye lymph nodes are located in the mesentery at the junction of the cecum to ileum, and includes 1 to 3 lymph nodes, but is most common lymph node 1-2.As a result, studies have identified features of the microscopic structure of the regional lymph nodes of the small intestine of Orenburg goat breed. Found that lymph nodes are composed of connective tissue core, the reticular and lymphoid tissue. Lymph nodes outside covered with well-defined capsule, consisting of several layers: a loose outer, intermediate and internal. Deep inside the capsule of the node depart cortical and medullary trabeculae. In the cortex are lymphoid nodules around which formed a diffuse lymphoid tissue. The latter is represented by lymphoid nodules, and cortical plateau, which distinguish the thymus-dependent and mezhuzelkovuyu paracortical zone.
