ANATOMY

Detailed explanation-1: -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-2: -Three layers of tissue form the heart wall. The outer layer of the heart wall is the epicardium, the middle layer is the myocardium, and the inner layer is the endocardium.

Detailed explanation-3: -The epicardium is the outermost layer of the heart. It is actually the visceral layer of the serous pericardium, which adheres to the myocardium of the heart. Histologically, it is made of mesothelial cells, the same as the parietal pericardium.

Detailed explanation-4: -Fibrous pericardium: This is the tough, outermost layer of your pericardium. It’s made of connective tissue that prevents your heart from expanding too much.

Detailed explanation-5: -The visceral serous pericardium, also known as the epicardium, covers the myocardium of the heart and can be considered its serosa.
