The muscular layer of the heart wall is the myocardium, which is responsible for the contraction of the heart and the pumping of blood throughout the body. The other options are not part of the muscular layer but rather the other layers of the heart wall: epicardium (outer layer), fibrous pericardium (protective layer), and endocardium (inner lining).
