    Oct 30, 2023 · The main function of the myocardium is to facilitate the contraction and relaxation of the heart walls in order to receive and pump the blood into the systemic circulation. In addition, the myocardial cells provide a scaffold for heart chambers and conduct electrical stimuli. Terminology. English: Myocardium.

    • 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.

    The inner endocardium lines the cardiac chambers, covers the cardiac valves, and joins with the endothelium that lines the blood vessels that connect to the heart. On the outer aspect of the myocardium is the epicardium which forms part of the pericardial sac that surrounds, protects, and lubricates the heart. [1]

    Nov 3, 2023 · The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. Branches of the heart’s conduction system are immersed into the subendocardial layer.

    Nov 7, 2024 · The myocardium is the thick, muscular middle layer of the heart wall responsible for the contractile function of the heart. It consists primarily of specialized cardiac muscle cells, known as cardiomyocytes, which have the unique ability to contract rhythmically and continuously throughout a person’s life. This layer is responsible for generating the force needed to
