Sternal angle's Interpretation of Nouns

Sternal angle, also known as "Cape Louis". It is the joint between the sternum stalk and the sternum body, slightly angled forward, connected by cartilage to form the sternoclavicular joint, and the two sides respectively form the sternoclavicular joint with the second costal cartilage, and the joint is slightly raised.

Extended data:

The symbolic significance of sternal angle:

1 and sternal angle are equivalent to the second front rib level, and the rib gap can be calculated in turn;

2. One of the most important bone markers in cardiology. During ECG operation, the right fourth intercostal space can be found according to sternal angle, so as to accurately find out the position of V 1 lead electrode;

3. It marks the bifurcation of bronchus, and tracheal bifurcation appears on this plane;

4. The junction of superior atrial margin and upper and lower mediastinum;

5. Body surface markers of aortic arch and the fourth thoracic vertebra;

6. The posterior plane is opposite to the lower edge of the fourth thoracic vertebra, which is also equivalent to the plane of the fifth thoracic vertebra;

7. The plane just passes through the window of aorta and pulmonary artery and is parallel to the starting point and ending point of aortic arch;

8. The azygos vein arch passes through the right lung root above this plane and flows forward into the superior vena cava;

9. The esophagus crosses the left main bronchus under this plane, forming a second esophageal stenosis;

10, under which the thoracic duct turns from the right side of the spine to the left side;

1 1, and the pulmonary artery bifurcation is located below this plane;

The distribution areas of 10 and T2 are equivalent to the sternal angle plane.
