Inferior mediastinum (overview)
- Anterior mediastinum (read more!) - lies between the sternum and pericardium;
- Middle mediastinum (read more!) - contains the heart covered by the pericardium;
- Posterior mediastinum (read more!)- lies between the pericardium and thoracic vertebrae.
Note: The transverse thoracic plane is a horizontal plane that passes through and connects the sternal angle to the intervertebral disc between the fourth and fiftth thoracic vertebrae. It divides mediastinum into two compartments - superior and inferior mediastinum.
