Accepted Answer

The pericardium consists of two layers: the outer fibrous pericardium and the inner serous pericardium. The serous pericardium is further divided into two layers, the visceral layer (also known as the epicardium) which adheres to the surface of the heart, and the parietal layer which lines the fibrous pericardium. The potential space between the visceral and parietal layers is called the pericardial cavity.
