A
- From the angle of the sternum to between the 4th and 5th intercostal spaces.
7
Q
What are the four main divisions of the mediastinum?
A
- the superior(above the horizontal plane), the anterior(anterior to pericardium), the middle(contains the heart and pericardium) and the posterior(below the pericardium).
8
