   The heart wall is composed of three layers: the epicardium, myocardium, and endocardium. Location of the heart in the mediastinum. The superficial epicardium is the visceral layer of the serous pericardium. The middle layer is the myocardium and is composed mainly of cardiac muscle and forms the bulk of the heart.

   Oct 30, 2023 · The heart contains three basic layers similar to those seen in arteries and veins. The outermost layer is the epicardium, which is derived from the proepicardium (from the septum transversum). The middle layer is the myocardium, and the innermost layer is the endocardium, which originated from mesothelial cells of the outflow tract.

   What are the two layers of the endocardium?

   • The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. Branches of the heart’s conduction system are immersed into the subendocardial layer.
