MICROANATOMY

Detailed explanation-1: -The epicardium is part of the pericardium. It is the innermost layer and is referred to as the visceral layer of the serous pericardium.

Detailed explanation-2: -The pericardium is a dual-layered structure enveloping the heart and proximal great vessels. It consists of an inner visceral pericardium (also called the epicardium when in contact with the myocardium), and an outer parietal pericardium, composed of layers of collagen fibrils and elastin fibers.

Detailed explanation-3: -The myocardium is the thickest of the three layers, particularly within the left ventricle, and is responsible for the ejection of blood during contractions. The epicardium (visceral pericardium) is responsible for the production of pericardial fluid and the protection of the other heart layers.

Detailed explanation-4: -Epicardium. The epicardium (visceral pericardium) is a serous membrane (serosa) of variable thickness, forming the outermost tunic of the heart. The connective tissue portion of this layer lies adjacent to the myocardium and is covered by a simple squamous epithelium (mesothelium) that faces the pericardial space.

Detailed explanation-5: -Serous pericardium The inner visceral layer that directly covers the organs in the cavity, that is, the heart. It is also called the epicardium as it is the outer covering of the heart.
