*The pleura covering the surface of the lung is known as '''Pulmonary Pleura''' or '''Visceral Pleura'''. This becomes continuous with the '''Mediastinal Pleura''' as it wraps around the lung.

*The '''Diaphragmatic''' and '''Costal Pleura''' are continuous with the Mediastinal Pleura. Together, these three membranes are the '''Parietal Pleura'''.

*Between the Parietal and Visceral Pleura is the '''Pleural Cavity'''. This contains a small amount of serous fluid which establishes adhesion between the layers and allows smooth movement.

*The Heart is invested in a Parietal and Visceral layer of '''Pericardium''' with the '''Pericardial Space''' separating the two membranes.

*Cranially the Costal and Mediastinal Pleura adjoin to form a 'dome' of pleura which extends cranially to the thoracic inlet. This is known as the '''Cupulae Pleurae'''. This region is only protected by soft tissue, and thus is vulnerable to injury.
