- The myocardium is located between the epicardium (outer layer) and the endocardium (inner layer) of the heart. It forms the bulk of the heart wall and is found in all four chambers of the heart, with the myocardium being thickest in the left ventricle, which is responsible for pumping oxygenated blood to the entire body.

- 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.
Nov 3, 2023 · The myocardium is functionally the main constituent of the heart and the thickest layer of all three heart layers. It is a muscle layer that enables heart contractions. Histologically, the myocardium is comprised of cardiomyocytes .
The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation.
Aug 8, 2023 · Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium.
Sep 2, 2023 · Cardiac muscle tissue is located in the middle of three layers of the heart, called the myocardium. Problems in the myocardium can cause heart failure and arrhythmias or contribute to sudden cardiac death.
