Detailed explanation-1: -The epicardium is the outermost layer of the heart. It is actually the visceral layer of the serous pericardium, which adheres to the myocardium of the heart. Histologically, it is made of mesothelial cells, the same as the parietal pericardium.
Detailed explanation-2: -The visceral serous pericardium, also known as the epicardium, covers the myocardium of the heart and can be considered its serosa. It is largely made of a mesothelium overlying some elastin-rich loose connective tissue.
Detailed explanation-3: -The visceral layer of the serous pericardium is also known as the epicardium.
Detailed explanation-4: -The pericardium is a dual-layered structure enveloping the heart and proximal great vessels. It consists of an inner visceral pericardium (also called the epicardium when in contact with the myocardium), and an outer parietal pericardium, composed of layers of collagen fibrils and elastin fibers.
