- 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.
Jun 11, 2024 · It has four main parts: two upper chambers called atria and two lower chambers called ventricles. These parts work together to get oxygen-rich blood to your body and oxygen-poor blood back to your heart.
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.
The area on the lower backside of the heart where the coronary sulcus meets the posterior interventricular sulcus is called the cardiac crux or crux of the heart. Coronary sulcus The coronary sulcus is also known as the atrioventricular groove.
Oct 20, 2024 · The pericardial sac consists of two fused layers: an outer fibrous layer and an inner parietal pericardial serous membrane. Between the pericardial sac and the heart is the pericardial cavity, which is filled with lubricating serous fluid.
Jan 4, 2024 · The epicardium is the outermost layer of the heart, formed by the visceral layer of the pericardium. It is composed of connective tissue and fat. The connective tissue secretes a small amount of lubricating fluid into the pericardial cavity.
