The term "pleura parietalis" refers to the outer layer of the pleura, which lines the walls of the thoracic cavity. The spelling of this term can be explained using the International Phonetic Alphabet (IPA): /pləˈrə paɪriəˈtælɪs/. The "p" sound at the beginning is followed by a short "u" sound, represented by the symbol "ə." The second word, "parietalis," includes a long "i" sound represented by "aɪ," and ends with "lɪs." Correct spelling is important in medical terminology, as precision and accuracy are essential for proper diagnosis and treatment.
Pleura parietalis, also known as the parietal pleura, is a term used in anatomy to denote the outer layer of the pleura, a thin and delicate membrane that lines the thoracic cavity and covers the lungs. The term "pleura" is derived from the Greek word "pleurum," meaning "side," as it is found along the sides of the thorax.
The pleura parietalis specifically refers to the portion of the pleura that lines the chest wall and the diaphragm. It is directly in contact with the inner surface of the ribs, the intercostal muscles, and the mediastinal structures. The parietal pleura is responsible for producing a small amount of serous fluid, which lubricates the pleural cavity and allows for the smooth movement of the lungs during breathing.
By covering the inner surface of the thoracic cage, the pleura parietalis plays a crucial role in protecting and supporting the lungs. It helps maintain the position and stability of the lungs within the thoracic cavity while providing a barrier against friction between the lungs and the chest wall during breathing movements.
In summary, the pleura parietalis is the outer layer of the pleura that lines the chest wall and the diaphragm. It contributes to the structural integrity and functioning of the respiratory system, ensuring the lungs can expand and contract smoothly within the thoracic cavity.
That which lines the different parts of the chest wall, called costal, diaphragmatic, mediastinal, and cervical according to the parts invested.

The term "pleura parietalis" is derived from Latin.
- "Pleura" comes from the Latin word "pleurēs", which refers to the lungs or the side of the body.
- "Parietalis" comes from the Latin word "pariēs", meaning "wall" or "partition".
Therefore, "pleura parietalis" in Latin can be understood as the "wall of the lungs" or "partition of the lungs". The term is commonly used in anatomy and medicine to refer to the outer layer of the membranes surrounding the lungs.
