Lumbar lymph nodes
The lumbar lymph nodes ( Lymphonodi [Lnn.] Lumbales or Nodi lymphoidei [Nll.] Lumbales ) are a group of lymph nodes in the retroperitoneal space of the lumbar region on the aorta .
In humans, there are three groups: Nodi lymphoidei lumbales dextri (right lumbar lymph nodes), Nodi lymphoidei lumbales intermedii (middle lumbar lymph nodes) and Nodi lymphoidei lumbales sinistri (left lumbar lymph nodes). The right and left lumbar lymph nodes receive their lymph from the kidneys , adrenal glands , ureters , testes or ovaries , fallopian tubes or vas deferens , the fundus of the uterus and the trunk wall. The middle lumbar lymph nodes lie between the aorta and the inferior vena cava .
In animal anatomy, the lumbar lymph nodes are assigned to the Lymphocentrum lumbale (lumbar lymph center). A distinction is made here between the segmental lumbar aortic lymph nodes located at the lumbar arteries ( arteriae lumbales ) of the aorta . The lymph node inflows behave like in humans. In ungulates , one or a group of these lymph nodes can be assigned directly to the kidney, which are then referred to as renal lymph nodes ( Lymphonodi renales ). In mares , lymph nodes specific for this organ (ovarian lymph nodes , Lymphonodi ovarici ) can occur in the anterior hanging ligament of the ovary , in boars in the vascular fold of the testicular artery testicular lymph nodes ( Lymphonodi testiculares ).
The outflow of the lymph from the lumbar lymph nodes takes place in the lymph collecting trunk of the loin ( truncus lumbalis ).
Diseases of the tributary area (i.e. the organs from which the lumbar lymph nodes receive their lymph) are usually expressed in a reaction of the lymph nodes ( lymphadenopathy ). In addition, metastases from tumor cells can settle in the lymph nodes .
