Epicardium
The epicardium (visceral pericardium, black arrows) is a serous membrane (serosa) of variable thickness, forming the outermost tunic of the heart. The connective tissue portion of this layer lies adjacent to the myocardium and is covered by a simple squamous epithelium (mesothelium) that faces the pericardial space. Coronary vessels, nerves and adipocytes are located in this layer. 10x, 100x
