Pleuritis Research Paper

Pleuritis or pleurisy is inflammation of the parietal pleura, which results in pleuritic chest pain. Pluera is consisted of two layers: inner layer called visceral pleura and outer layer called parietal pleura. While the visceral pleura does not have nocicpetors and does not give rise to the pain sensation, the parietal pleura can sense pain when inflamed, since it is innervated by numerous somatic nerves that have somatic pain receptors. Between the two layers, there is a space called pleural space that has a thin layer of fluid, and its function is to lubricate the pleural surfaces when breathing. When the surfaces become roughened and inflamed because of pus-filled pleura, nociceptive receptors in the parietal pleura are stimulated and activated
