Mediastinum Posterior

The posterior mediastinum is the part of the lower mediastinum located between the posterior surface of the pericardium and the spine. It contains the following anatomical structures:

1. Lower esophagus
2. Descending aorta
3. Azygos and semi-amygos veins
4. Thoracic duct
5. The lymph nodes
6. Nerve plexuses
7. Vagus nerves
8. Sympathetic trunks

The posterior mediastinum is also called the posterior mediastinal space (cavum mediastinale posterius) or the posterior part of the mediastinum (pars dorsalis mediastini). This space is located posterior to the roots of the lungs and is separated from the anterior mediastinum by the thoracic aorta, azygos and semi-gypsy veins.

Thus, the posterior mediastinum is an important anatomical space containing structures of the digestive, cardiovascular, lymphatic and nervous systems.

The mediastinum is the space inside the chest, which is filled with tissues, organs and vessels that support human life. The posterior mediastinum has a complex structure that includes many important organs and structures, such as the esophagus, descending aorta, vagus nerve and sympathetic trunk.

The posterior mediastinum separates the upper and posterior sections of the thoracic cavity from its lower section. The area is medial to the posterior border of the thymus and parasternal muscles. The posterior surface of the mediastinal region is covered posteriorly by the pericardium, superiorly by the mediastinum
