The myocardium is the muscular wall of the heart, or the heart muscle. It contracts to pump blood out of the heart and then relaxes as the heart refills with returning blood. The endocardium is the innermost layer of tissue that lines the chambers of the heart.
The serous pericardium is composed of two continuous layers that surround the heart. The visceral layer, also known as the epicardium, directly adheres to and lines the heart’s itself, making it the innermost layer of the pericardium and the outermost layer of the heart wall.

- 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.
Jan 4, 2024 · The heart wall itself can be divided into three distinct layers: the endocardium, myocardium, and epicardium. In this article, we shall look at the anatomy and clinical relevance of these layers.
The wall of the heart is composed of three layers of unequal thickness. From superficial to deep, these are the epicardium, the myocardium, and the endocardium (see Figure 19.5 ). 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.
