Nov 3, 2023 · 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.

- Epicardium. Epicardium (epi-cardium) is the outer layer of the heart wall. It is also known as visceral pericardium as it forms the inner layer of the pericardium.
- Myocardium. Myocardium (myo-cardium) is the middle layer of the heart wall. It is composed of cardiac muscle fibers, which enable heart contractions. The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart.
- Endocardium. Endocardium (endo-cardium) is the thin inner layer of the heart wall. This layer lines the inner heart chambers, covers heart valves, and is continuous with the endothelium of large blood vessels.
The outer layer is called the epicardium, or visceral pericardium, since it is also the inner wall of the pericardium. The middle layer of the heart, the myocardium, and contains specialized cardiac muscle tissue responsible for contraction.
Jun 11, 2024 · Epicardium: The outermost layer protects the heart and reduces friction with surrounding structures. Understanding the heart's external and internal anatomy is essential for comprehending how this organ functions to maintain blood circulation throughout the body.
The outer layer of the heart wall is the epicardium. The epicardium refers to both the outer layer of the heart and the inner layer of the serous visceral pericardium, which is attached to the outer wall of the heart.
Oct 20, 2024 · The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier. The multi-layered membrane that directly surrounds the heart and defines the pericardial cavity is called the pericardium or pericardial sac .
The outer longitudinal layer at the apex of the heart creates the vortex of the heart - the swirling arrangement of cardiac muscular fibers at the apex of the heart. At the mentioned site, the outer longitudinal layer transitions into the inner longitudinal layer.
