A)The heart wall consists of three layers of tissue: the epicardium, the myocardium, and the endocardium. The epicardium covers the entire heart and great vessels, and then folds over to form the parietal layer lining the pericardium and adheres to the heart surface. The myocardium, the middle layer of the heart wall, consists of specialized cardiac muscle cells (myofibrils). The endocardium, which is the innermost layer, is a thin membrane composed of three layers. The myocardium is the muscular layer of the heart that contracts during each heartbeat. The outermost layer of the heart is the epicardium.
