Diaphragmomediastinal Sinus

The phrenic-medistinal sinus or phrenic-mediastinal recess is an anatomical formation that is a depression in the diaphragm located between its costal and mediastinal parts. This depression has a triangular shape and is limited on three sides by the costal part of the diaphragm, and on the fourth by the mediastinal part.

The diaphragmomedistinal recess plays an important role in human anatomy, as it is one of the pathways through which vessels and nerves pass connecting the thoracic cavity to the abdominal cavity. In addition, this depression can be used to house certain organs such as the liver, gallbladder and pancreas.

In medical practice, the phrenic-medistinal sinuses can be involved in various diseases, such as hiatal hernia, diaphragmatic hernia and other diseases. A surgeon can use knowledge of the anatomy of the diaphragm in his work to determine the location of the phrenic-medistinal sinuses in order to avoid damage to important organs and vessels during abdominal surgery.

Thus, the diaphragmomedistinal sinus is an important anatomical structure that plays a role in connecting the thoracic and abdominal cavities, and can also be used in medical practice in the treatment of various diseases.

The diaphragmomediastinal sinus is an anatomical formation that is located between the diaphragm and the mediastinal fascia. It plays an important role in the functioning of the respiratory system and is one of the components of the diaphragm.

The diaphragmomediastinal sinus is a depression located on the posterior surface of the diaphragm and bounded above by the mediastinal fascia and below by the hepatorenal ligament. The recess has the shape of a triangle, the base of which is directed downward and backward.

The diaphragmomediastial sinus contains blood vessels, nerves and lymphatic vessels. There are also airways that connect the lungs to the pleural cavity. In addition, the phrenic mediastinal sinus contains lymph nodes that play an important role in the immune system.

The functioning of the diaphragmomediastial sinus is closely related to the respiratory system. During inhalation, the diaphragm lowers, which leads to a widening of the cavity and an increase in lung volume. During exhalation, the diaphragm rises, which narrows the cavity and reduces lung volume.

Thus, the diaphragmomediastinal sinus plays an important role in maintaining the normal functioning of the respiratory system. It provides a connection between the lungs and the pleural cavity, and also participates in the formation of pulmonary volume.
