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.
