When the visceral layer comes into contact with heart (not the great vessels) it is known as the epicardium. The epicardium is the layer immediately outside of the heart muscle proper (the myocardium). The epicardium is largely made of connective tissue and functions as a protective layer.he serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium.
The left auricle is a thin pouch of the heart wall located on the anterior surface of the left atrium. Its walls are only about one sixteenth of an inch (1 mm) in thickness and less than 1 inch (2.5 cm) in length. The outermost layer of the auricle is the epicardium, a layer of simple squamous epithelial tissue that gives the auricle a smooth, slick surface. 2  Pericardial fluid is produced by the epicardium to lubricate its surface and prevent irritation during the movement of the heart.
