Detailed explanation-1: -The epicardium of the heart is the layer of the heart wall immediately superficial to the myocardium and deep to the pericardial cavity. It forms the innermost, visceral layer of the serous pericardium. It is formed from a layer of contiguous mesothelial cells.
Detailed explanation-2: -The endocardium forms the inner lining of the heart, and the flaps which form the valves of the heart.
Detailed explanation-3: -The epicardium, or the innermost layer of the pericardium, is the outermost layer of the heart itself. It is composed of mesothelial cells, fat, and connective tissue. It is adjacent to the myocardium, the middle muscular layer. The innermost layer is referred to as the endocardium.
Detailed explanation-4: -The epicardium is a mesothelium. Mesothelia line or cover body spaces such as the peritoneal, pleural, and pericardial cavities and provide a smooth surface on which organs move. In addition, this specialized simple squamous epithelial structure provides a barrier in the compartmentalization of body spaces.
