PLEURA PERICARDIACA Meaning and
Definition
-
Pleura pericardiaca refers to the thin membrane or layer of tissue that surrounds the pericardium, which is the fluid-filled sac that encloses the heart. The term "pleura" pertains to a serous membrane found in the thoracic cavity that lines the lungs and surrounds the organs within this region. Consequently, the pleura pericardiaca encompasses the portion of the pleural membrane that is anatomically related to the pericardium, the protective covering of the heart.
The pleura pericardiaca consists of two layers: the outer layer, called the parietal pleura, which lines the inner surface of the pericardium, and the inner layer, referred to as the visceral pleura, which covers the heart itself. The space between these two layers is known as the pericardial cavity, and it contains a small amount of serous fluid that lubricates the movement of the heart, allowing it to beat smoothly without friction.
The pleura pericardiaca has a crucial role in protecting and supporting the heart, as it helps to anchor the organ within the thoracic cavity and prevents excessive movement that could potentially lead to damage or improper function. Additionally, the pleura pericardiaca aids in maintaining the stability of the pericardium and its connection to the neighboring structures, such as the sternum and diaphragm.

Etymology of PLEURA PERICARDIACA
The term "pleura pericardiaca" is a combination of two anatomical terms: "pleura" and "pericardiaca".
1. Pleura: The word "pleura" originates from the Ancient Greek word "pleuron", meaning "side". In anatomy, the pleura refers to the two thin membranes that line the thoracic cavity and cover the lungs. The pleura helps to protect and lubricate the lungs during breathing.
2. Pericardiaca: The term "pericardiaca" is derived from the word "pericardium". "Pericardium" is a combination of two Latin words, "peri" meaning "around" and "cardium" meaning "heart". The pericardium is a double-layered sac that surrounds and protects the heart.
