   • 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 10, 2024 · Myocardium:The myocardium is the thick, muscular middle layer of the heart wall and is composed of cardiomyocytes (heart muscle cells). The myocardium is responsible for the contractile force of the heart. It is thickest in the left ventricle, which must generate enough force to pump blood throughout the entire body.

   What is the thickest layer of the heart wall?

   • The myocardium is the thickest layer of the heart wall, with its thickness varying in different parts of the heart. The myocardium of the left ventricle is the thickest, as this ventricle is responsible for generating the power needed to pump oxygenated blood from the heart to the rest of the body.
