In what major cavity can the mediastinum be found? The mediastinum is a large anatomic compartment in the thoracic cavity, bounded laterally by the pleurae, anteriorly by the sternum, posteriorly by the vertebrae, superiorly by the thoracic inlet, and inferiorly by the diaphragm.
Is the mediastinum located in the center of the abdominal cavity? The mediastinum is the central compartment of the thoracic cavity, located between the two pleural sacs. It contains most of the thoracic organs, and acts as a conduit for structures traversing the thorax on their way into the abdomen.

What is mediastinum and its types?
The mediastinum is an area found in the midline of the thoracic cavity, that is surrounded by the left and right pleural sacs. It is divided into the superior and inferior mediastinum, of which the latter is larger. The inferior mediastinum is further divided into the anterior, middle and posterior mediastinum.
Where does the mediastinum start?
The superior mediastinum starts at the superior thoracic aperture and ends at the thoracic plane.
How does the heart sit in the chest cavity?
The Heart Is Located in the Center of the Thoracic Cavity. The pericardium is fused to the diaphragm, and so downward movement of the diaphragm during inspiration pulls the heart into a more vertical orientation. The heart sits atop the diaphragm and its apex is close to the anterior surface of the thoracic cavity.
