Epicardium

The epicardium is the outermost layer of the heart wall, also known as the visceral pericardium. It is made up of a single layer of flattened mesothelial cells that covers the entire surface of the heart. It acts as a protective barrier for the heart, providing mechanical protection as well as preventing infection. Furthermore, it serves as a conduit for the conduction of electrical signals to the heart muscle and vascular system. By secreting hormones and cytokines, the epicardium also plays a role in maintaining the integrity of the myocardium and regulating the growth, development and function of the heart. In addition, it is involved in the wound healing process of the heart. It is therefore a crucial part of the heart anatomy and its importance cannot be overstated.
