What is an excellent mediastinum?
mediastinum, sometimes divided into "medial stinum" or the "media-stinum" fastener, is the inner body cavity behind the center of the chest or thoracic bone. It is traditional to divide into two areas: lower rear and upper boss. Excellent mediastinum or upper chest for common references is a particularly medical interest, because the structures of human anatomy anatomy contained in it generally represent the main connectors between the head and the body. These structures are freely organized and held together with soft connective tissue. The relatively narrow space is bounded on each side with lungs. It starts at the top, from the thoracic hole at the base of the neck and reaches down to the large membrane muscle that operates the lungs.
The definition between the rear and superior Medidiastinum is somewhat arbitrary but widely agreed. This division is a horizontal plane passing through the lower edge of the T4 or the fourth upper thoracic vertebra with the lower edge of the Sterni Manubria. This is enlarged, quadrangular shaped bone of the highest thoracicku. The first two rib bones are connected.
This plane neatly clicks the upper edge of the heart. Therefore, one of the most important structures in the superior mediastin is aorta, a massive blood vessel that argues over the heart and down to the whole body. It carries oxygenated blood. Other equally important tubular structures include trachea or trachea and esophagus for food.
Most nerves connecting the head and the body are connected to the spinal cord in the spine. However, the brain requires a more direct connection for some critical organs or physical entertainment. Some of these nerves, including the heart nerve that control the heart, pass through the superior mediastin. The French nerve associates with the muscle of the diaphragm that controls breathing. Vagus nerves collect all the sensory nerves from most other internal organs of the body to advise the brain of their functional state.
Holy Channel that passes throughout the MediaIt is the largest container of the human lymphatic system. Its branching, body network containing pure liquid called lymphale is not unlike the human circulatory system. In cooperation with blood in its network, these two systems form the body's immune system to filter and combat invasive, potentially harmful substances such as viruses. One of the few completely independent bodies in the superior mediastin is the thymus. Its only known function is connected to the lymphatic system, it is to produce the so-called T-cells, the most effective combatants of the immune system.
