Pleurisy is inflammation of the pleural membranes. It is most commonly caused by a viral infection, but may also be the result of a bacterial infection or an autoimmune disease (such as rheumatoid arthritis or lupus).
Your pleura is a thin membrane that lines your chest wall and lungs. It cushions your lungs and makes breathing easier. Infections and chest injuries can damage your pleura and affect your ability to breathe.
The pleurae refer to the serous membranes that line the lungs and thoracic cavity. They permit efficient and effortless respiration. This article will outline the structure and function of the pleurae, as well as considering the clinical correlations.
The pleurae are two layers of serous membrane that form the boundaries of the pleural cavity. There are two types of pleura; parietal and visceral. The parietal pleura is the thicker and more durable outer layer that lines the inner aspect of the thoracic cavity and the mediastinum.
The pleura is a double-layered serous membrane that covers each lung and lines the thoracic cage. The outer layer (parietal pleura) attaches to the chest wall. The inner layer (visceral pleura) covers the lungs, neurovascular structures of the mediastinum and the bronchi.
As a serous membrane, the pleura secretes a serous fluid (pleural fluid) that contains various lubricating macromolecules such as sialomucin, hyaluronan and phospholipids.
A pleura is a serous membrane that folds back on itself to form a two-layered membranous pleural sac. The outer layer is called the parietal pleura and attaches to the chest wall. The inner layer is called the visceral pleura and covers the lungs, blood vessels, nerves, and bronchi.
The pleurae are paired linings, located within the thoracic cavity, that surround each lung and separate them from the thoracic wall. They reflect upon themselves to form two layers of thin, serous membranes that glisten and appear grayish-yellow in color. A potential space called the pleural cavity forms between these layers.
The pleurae are serous membranes which fold back onto themselves to form a two-layered membranous structure. The thin space between the two pleural layers is known as the pleural cavity and normally contains a small amount of pleural fluid.
Disorders of the pleura and pleural space reflect some of the oldest diseases encountered in surgical history. Hippocrates described the symptoms of empyema 2400 years ago: “Empyema may be recognized by the following symptoms: In the first place the fever is constant, less during the day and greater at night, and copious sweats supervene.
