The middle layer of the heart wall is the myocardium—the muscle tissue of the heart and the thickest layer of the heart wall. It is composed of cardiac muscle cells, or cardiomyocytes. Cardiomyocytes are specialized muscle cells that contract like other muscle cells, but differ in shape.
Aug 4, 2023 · The endocardium is the innermost layer of the heart wall lining the internal chambers of the heart and the heart valves. It provides a smooth surface for efficient blood flow inside the heart chambers.
Oct 30, 2023 · The myocardium is the middle muscular layer of the heart. It is the thickest layer which lies between the single-cell endocardium layer, and the outer epicardium, which makes up the visceral pericardium that surrounds and protects the 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.
