The correct spelling of "pleura costalis" is pronounced /ˈplʊrə kɒˈsteɪlɪs/. The word "pleura" refers to a thin membrane surrounding the lungs, while "costalis" means related to the ribs. The first part of the word, "pleura," is spelled with a silent "e" and a long "u" sound, represented by the IPA symbol /ˈplʊrə/. The second part, "costalis," is pronounced with a hard "c" and a long "o," represented by the IPA symbol /kɒˈsteɪlɪs/. Together, these words refer to the membrane that surrounds the lungs and attaches to the ribs.
The term "pleura costalis" refers to the anatomical structure located in the chest cavity, specifically the pleura that lines the inner surfaces of the ribs. The chest cavity, also known as the thoracic cavity, contains vital organs such as the heart and lungs, and the pleura costalis plays a crucial role in protecting and facilitating their movement.
The pleura costalis consists of two layers: the parietal pleura and the visceral pleura. The parietal pleura lines the inner surface of the rib cage and upper surface of the diaphragm, while the visceral pleura covers the external surface of the lungs. Between these two layers is a thin, fluid-filled space known as the pleural cavity, which allows for smooth, frictionless movement of the lungs during respiration.
The pleura costalis serves several important functions. Firstly, it provides a protective barrier for the lungs, preventing friction and damage due to the constant movement during breathing. Secondly, it allows the lungs to expand and contract effortlessly by facilitating the gliding motion of the lungs against the chest wall during respiration. Additionally, the pleura costalis assists in maintaining a balance of pressure within the pleural cavity, which is essential for efficient lung function.
In summary, the pleura costalis is the name given to the pleural lining found along the inner surfaces of the ribs. It is responsible for protecting the lungs, promoting their movement, and maintaining a harmonious pleural cavity pressure for proper functioning.

The word "pleura" is derived from the Latin word "pleura" which means "rib". It is used to refer to the membranous lining of the chest cavity.
The word "costalis" comes from the Latin word "costa" which means "rib". It is used to describe something related to the ribs.
Therefore, "pleura costalis" can be translated as "rib-like pleura" or "pleura of the ribs", indicating the specific location of the pleural membrane lining which is adjacent to the ribs.
