Final answer:
The correct sequence of the pericardial layers from the outermost to the innermost is the fibrous pericardium, parietal pericardium, pericardial cavity, and the epicardium (visceral pericardium).
Step-by-step explanation:
The provided statement is indeed false. The layers surrounding the heart form a protective and lubricating structure known as the pericardium. The correct order of these layers, from superficial to deep, is as follows: fibrous pericardium, parietal pericardium, pericardial cavity, and epicardium (or visceral pericardium).
The outermost layer is the fibrous pericardium, a tough and protective sac that encases the heart. This layer provides structural support and anchors the heart within the thoracic cavity.
Beneath the fibrous pericardium lies the parietal pericardium, which lines the inner surface of the fibrous layer. The parietal pericardium forms a double-layered sac with the visceral pericardium, collectively known as the serous pericardium.
Within the serous pericardium, there exists the pericardial cavity, a potential space between the parietal and visceral layers. This cavity is filled with a lubricating fluid called pericardial fluid, which allows for smooth movement and reduces friction as the heart beats and contracts.
The innermost layer is the epicardium, which is synonymous with the visceral pericardium. This layer closely adheres to the surface of the heart muscle and is an integral part of the heart wall.
In summary, the correct arrangement of the layers surrounding the heart, from superficial to deep, is fibrous pericardium, parietal pericardium, pericardial cavity, and epicardium (or visceral pericardium). Each layer contributes to the overall protection, lubrication, and structural integrity of the heart.
