The wall of the heart consists of three Tunics (layers) : the internal or endocardium, the middle or myocardium and the external or pericardium.

The endocardium is a single layer of squamous endothelial cell resting upon thin layer of loose connective tissue.

The pericardium is the serous covering of the heart. It has three layers.

The myocardium or the middle layer is the thickest of the tunics. It consists of cardiac muscle cells.
