Study Notes
Mediastinum Location and Divisions
- The mediastinum is located in the thoracic cavity, between the two pleural sacs that surround the lungs.
Divisions of the Mediastinum
- The superior and inferior mediastinum are divided by an imaginary line that intersects the fourth thoracic vertebra (T4).
Arteries in the Superior Mediastinum
- The superior mediastinum contains the brachiocephalic arteries, which are branches of the arch of the aorta.
Anterior Mediastinum
- The anterior mediastinum, also known as the anterior middiastinum, is the part of the mediastinum that lies anterior to the heart.
