     • 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 3 layers of the heart?

    • The Heart Wall: The wall of the heart is composed of three layers, the thin outer epicardium, the thick middle myocardium, and the very thin inner endocardium. The dark area on the heart wall is scarring from a previous myocardial infarction (heart attack). The outer layer of the heart wall is the epicardium.

    What is the thickest layer of the heart wall?

    • The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart. The myocardium of the left ventricle is the thickest, as this ventricle is responsible for generating the power needed to pump oxygenated blood from the heart to the rest of the body.

    What is the middle layer of the heart?

    • 2. Myocardium (Middle Layer of Heart) Myocardium is the middle thickest muscular layer made up of cardiomyocytes. It is responsible for the contraction and relaxation actions of the heart. The SA (sinoatrial) and the AV (atrioventricular) nodes of the heart conduction system are mostly located in this layer.
