Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, with the other two being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart. The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation. It is com… WebDifferent layers of the tricuspid and mitral valves include the atrialis (on the atrial side), spongiosa, fibrosa, and ventricularis (on the ventricular side). Beyond the proximal ½ of the valve, the valve is avascular and these different layers are not readily appreciable.

WebBelow the epicardium, there is a thick muscular layer called the myocardium. Then, finally, we reach the thin inner layer of the heart, which is the endocardium. Endocardium layers.
