Explanation:
The serous membrane that envelopes and protects the heart in the pericardial cavity is the pericardium. Pericardium is divided into two types – the fibrous pericardium and the serous pericardium.
The outer fibrous pericardium composed of connective tissue anchors the heart firmly to the walls, and prevents overfilling of blood.
The inner serous pericardium lies next to the fibrous pericardium, and divided into two layers – the outer parietal and the inner visceral layer.
The parietal layer is attached to the fibrous pericardium
The visceral layer is inner and is continuous with the epicardium of the heart.
Hence, the epicardium is considered the visceral pericardium and not the parietal pericardium
