PARIETAL PLEURA Meaning and
Definition
-
The parietal pleura is a term used in the field of anatomy to describe a specific membrane that lines the thoracic cavity and covers the walls of the chest. This double-layered, serous membrane plays a crucial role in protecting and lubricating the lungs during respiration.
The parietal pleura consists of two distinct layers: the outer layer, known as the parietal pleura, and the inner layer, known as the visceral pleura. The parietal pleura is further divided into several regions, including the costal, diaphragmatic, and mediastinal portions, which respectively encompass the ribs, the diaphragm (a muscle that separates the thoracic and abdominal cavities), and the middle region of the thoracic cavity.
The parietal pleura functions to provide a protective lining for the thoracic cavity, reducing friction and allowing for smooth and effortless movement of the lungs during breathing. It also assists in maintaining the negative pressure within the thoracic cavity, which helps the lungs to expand and contract effectively during respiration.
In addition to its protective and lubricating functions, the parietal pleura contains numerous blood vessels, lymphatics, and nerve endings that play important roles in the systemic circulation, lymphatic drainage, and sensory perception within the thoracic cavity.

Etymology of PARIETAL PLEURA
The term "parietal pleura" is derived from Latin and Greek origins.
The word "parietal" comes from the Latin word "paries", which means "wall". In the context of the pleura, it refers to the outer layer of the pleural membrane that lines the thoracic cavity. The parietal pleura is attached to the chest wall, ribs, and diaphragm.
The word "pleura" originates from the Greek word "pleuron", meaning "side". In Greek anatomy, "pleura" was used to describe the membrane that covered the lungs and lined the thoracic cavity.
Therefore, the term "parietal pleura" refers to the outer layer of the pleural membrane that lines the interior walls of the thoracic cavity.
