Mediastinal lymph nodes
As Mediastinallymphknoten ( lymph nodes [Nll.] Mediastinales , lymphonodi [lnn.] Mediastinales) are lymph nodes which have in the mediastinum are within the thorax.
There are two groups in humans:
- The Nodi lymphatici mediastinales anteriores ("anterior mediastinal lymph nodes") lie behind the breastbone , in front of and behind the thymus and in front of the pericardium and the large blood vessels near the heart . The lowest anterior mediastinal lymph nodes lie against the diaphragm and are therefore also called Nll. phrenici . Their tributary areas are the liver , pericardium, heart and thymus. Lymph drainage takes place via the anterior mediastinal trunk into the venous angle .
- The Nodi lymphatici mediastinales posteriores ("posterior mediastinal lymph nodes") lie next to the esophagus and aorta . Their tributary areas are the liver, diaphragm, esophagus, lungs and the back part of the intercostal spaces . The lymphatic drainage is via the bronchomediastinal trunk , the left into the thoracic duct , right along with the trunk mediastinal anterior , the jugular trunk and subclavian trunk into the right lymphatic duct empties.
In veterinary anatomy, the mediastinal lymph nodes are grouped together to form the Lymhocentrum mediastinale . According to the relationship to the heart, there are three groups:
- The Lymphonodi mediastinales craniales ("anterior mediastinal lymph nodes") are located at the entrance to the breast.
- The Lymphonodi mediastinales medii ("middle mediastinal lymph nodes") lie at the base of the heart. They are absent in predators and pigs.
- The Lymphonodi mediastinales caudales ("posterior mediastinal lymph nodes") lie behind the heart on the esophagus. They are absent in predators and goats.
The tributary area of the mediastinal lymph nodes includes all organs of the mediastinum, parts of the chest wall, shoulder and neck, as well as the lungs and pleura . In horses and cattle there are also tributaries from the liver and spleen.
