Blood Supply
- The blood supply for the parietal pleura is from the internal thoracic arteries, intercostal arteries, and phrenic arteries.
Mediastinum Divisions
- The posterior mediastinum contains the esophagus, two vagi, and descending aorta & its branches.
Pain Sensitivity
- The pleura is not sensitive to pain.
Mediastinum Subdivisions
