Lumbar lymph nodes

The lumbar lymph nodes ( lymph [ Lnn. ] Or lumbar lymph nodes [ lymph ]. Lumbar ) are a group of lymph nodes in the retroperitoneal space of the lumbar region of the aorta.

In humans, there are three groups: lumbar lymph nodes dextri (right lumbar lymph nodes), lumbar lymph nodes intermedii (mean lumbar lymph nodes) and lumbar lymph nodes sinistri (left lumbar lymph nodes). The right and left lumbar lymph nodes receive lymph from their kidneys, adrenal glands, ureters, testes or ovary, fallopian tubes or vas deferens, the fundus of the uterus and the fuselage wall. The mean lumbar lymph nodes located between the aorta and inferior vena cava.

In animal anatomy, the lumbar lymph nodes are assigned to the Lymphocentrum lumbar ( Lendenlymphzentrum ). We distinguish the segmental lumbar arteries to the disposals ( lumbar arteries ) of the aorta lying lumbar aortic lymph. The lymph nodes inflows behave like humans. In ungulates can assign one or a group of these lymph nodes directly to the kidney, which then as Nierenlmyphknoten ( lymph renales) are referred to. Mares in front suspensory ligament of the ovary can be used for this organ -specific lymph nodes ( lymph nodes, ovary, lymph ovarici ), the boar in the vascular fold of testicular artery testicular lymph nodes ( lymph testiculares ) occur.

The flow of lymph from the lumbar lymph nodes occurs in the Lymphsammelstamm the loin ( lumbar trunk ).

Diseases of the tributary area (ie the organs, of which the lumbar lymph nodes receive their lymph) usually manifest themselves in case of a reaction of the lymph nodes ( lymphadenopathy). In addition, to settle in the lymph node metastasis of tumor cells.
