Study Notes
Mediastinum Overview
- The mediastinum is a highly mobile area.
Structures in the Mediastinum
- The mediastinum contains various structures such as the heart, trachea, esophagus, and major blood vessels.
Structures NOT Found in the Mediastinum
- The mediastinum does not contain the lungs or the diaphragm.
Mobility of the Mediastinum
- The mediastinum's mobility is due to the lack of fixed attachments between the thoracic vertebrae and the sternum.
Extent of the Mediastinum
- The mediastinum extends from the thoracic inlet (superiorly) to the diaphragm (inferiorly).
Boundaries of the Mediastinum
- The mediastinum is bounded by the thoracic vertebrae (posteriorly), the sternum (anteriorly), the lungs (laterally), and the diaphragm (inferiorly).
Subdivisions of the Mediastinum
- The mediastinum is divided into the superior mediastinum and the inferior mediastinum, which is further divided into the anterior, middle, and posterior mediastinum.
Changes in Mediastinum Mobility with Age
- The mobility of the mediastinum decreases with age due to the increasing stiffness of the thoracic vertebrae and the sternum.
