Parietal layer of serous pericardium: It lines the fibrous pericardium and is reflected around the roots of great blood vessels. At the region of reflection, it becomes continuous with the visceral layer of serous pericardium, which covers the heart closely.Visceral layer of serous pericardium: This layer is closely applied to the heart and is often called the epicardium.There exists a slit like space between the parietal and visceral layers of serous pericardium. This space is known as pericardial cavity and it contains a small amount of tissue fluid called pericardial fluid.ericardium is a fibroserous sac, which encloses the heart and roots of great vessels. It has two primary functions. Firstly, it restricts excessive movements of the heart so that injury to this vital organ of human body is avoided.
The serous pericardium (fig. 23-1) is a closed sac, the parietal layer of which lines the inner surface of the fibrous pericardium and is reflected onto the heart as the visceral layer, or epicardium.3-1 The transverse sinus of the pericardium is a passage between the venous end (left atrium and superior vena cava) of the heart behind and the arterial end (aorta and pulmonary trunk) in front (see fig. 23-2 A).
