The pleurae (sg.: pleura) [1] are the two flattened closed sacs filled with pleural fluid, each ensheathing each lung and lining their surrounding tissues, locally appearing as two opposing layers of serous membrane separating the lungs from the mediastinum, the inside surfaces of the surrounding chest walls and the diaphragm. Although wrapped ...
The pleural cavity, or pleural space (or sometimes intrapleural space), is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes , and also to create a pressure gradient .
Called the pericardium, this serous membrane is a two-layered sac that surrounds the entire heart except where blood vessels emerge on the heart's superior side; [4] The pleura is the serous membrane that surrounds the lungs in the pleural cavity; The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity.
The function of the suprapleural membrane is to protect the apex of the lung (as some of the part which extends outside the rib cage) and to protect the cervical fascia. This helps in resisting intrathoracic pressure changes therefore preventing inflation and deflation of the neck during expiration and inspiration respectively and also ...

This fascial layer is the outermost membrane of the thoracic cavity. The endothoracic fascia contains variable amounts of fat. It becomes more fibrous over the apices of the lungs as the suprapleural membrane. It separates the internal thoracic artery from the parietal pleura.
