The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart. The outer layer of the heart is termed epicardium and the heart is surrounded by a small amount of fluid enclosed by a fibrous sac called the pericardium. 1 Function.
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.
