Arteries Diaphragmatic Superior

Arteries Diaphragmatic Superior: anatomy and functions

The superior phrenic arteries (abbreviated PNA and BNA) are important structures that provide blood supply to the diaphragm, the main muscular respiratory organ of humans.

The superior phrenic arteries originate from the inferior superficial branches of the internal mammary artery and are directed downward and outward along the edge of the diaphragm. When they reach the edge of the diaphragm, they make an acute angle and go back, forming an arc that runs along the edge of the diaphragm and forms an anastomosis with the second pair of arteries of the diaphragm - the inferior phrenic arteries.

The superior phrenic arteries play an important role in providing blood supply to the diaphragm and adjacent organs such as the liver, spleen and stomach. They also provide blood supply to the adrenal glands and kidneys.

In addition, the superior phrenic arteries may play an important role in surgical procedures such as liver resection or adrenal removal. In such cases, knowledge of the anatomy and location of the superior phrenic arteries is important to prevent damage to these structures during surgery.

In conclusion, the superior phrenic arteries are important structures providing blood supply to the diaphragm and adjacent organs. Knowledge of their anatomy and functions is of great importance in surgical practice and can help avoid complications during surgery.

What are the phrenic arteries? The diaphragm can be separated and stripped of its nerve endings and bundles, resulting in complete loss of its own neural regulation. In some cases, the nerves that may be involved in creating oscillations in the diaphragm may also be absent. Compensation will not work in this case. To prevent nerve disorders associated with interrupted nerve fibers, some obstetricians recommend massaging the diaphragm with your fingers and tongue to restore nerve connections.

The superior diaphragm is an arterial branch of the esophagus and runs along the right border of the body. Approaching the mouth of the trachea, the arch branches, forming pulmonary branches, then gradually forms larger diagonal branches on the neck and head. When the tracheal-arch opening becomes a branch, two branches arise from each arch of the blood artery. Retrospinally, the diagram leaves as the renal and superior gastric arteries, while through the anterior chest wall it follows the anterior curvature of the esophagus.
