THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The epicardium, or the innermost layer of the pericardium, is the outermost layer of the heart itself. It is composed of mesothelial cells, fat, and connective tissue. It is adjacent to the myocardium, the middle muscular layer. The innermost layer is referred to as the endocardium .

Detailed explanation-2: -The walls of the heart are composed of three layers: Epicardium-the outer layer. Myocardium-the middle, muscular layer. Endocardium-the inner layer.

Detailed explanation-3: -The Pericardium. The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.

Detailed explanation-4: -Epicardial fat covers 80% of the heart’s surface and constitutes 20% of total heart weight. It is present along the distribution of the coronary arteries, over the right ventricle especially along the right border, anterior surface and at the apex.
