- 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.
