The myocardium is the middle muscular layer of the heart's walls and it functions by providing a scaffolding for the heart chambers, assisting in contraction and relaxation of the cardiac walls so that blood can pass between the chambers and electrostimulation conduction through its own tissues and into the epicardium.
The endocardium is a thin layer of endothelium that lines the chambers of the heart and the valves. The pericardium (around the heart) is a triple-layered fluid-filled sac that surrounds the heart. The outer layer of this sac is the fibrous pericardium . It is a strong layer of dense connective tissue.
