Q

3 Layers of the Heart (outermost to innermost):

A

(1) Epicardium (Visceral Serous Layer): thin external layer formed by visceral layer of serous pericardium
(2) Myocardium: thick middle layer composed of cardiac muscle
(3) Endocardium: thin internal layer that covers the chambers of the heart and the valves
