Nov 3, 2023 · It lines the inner surfaces of the heart chambers, including the heart valves. 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 ...

- 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.
Mar 24, 2022 · The heart is made of three layers of tissue. Endocardium is the thin inner lining of the heart chambers and also forms the surface of the valves. Myocardium is the thick middle layer of muscle that allows your heart chambers to contract and relax to pump blood to your body. Pericardium is the sac that surrounds your heart. Made of thin layers ...
Mar 2, 2024 · The endocardium is located inside the heart, lining the chambers (the two atria and two ventricles) and extending to cover the heart valves (tricuspid, pulmonary, mitral, and aortic valves). It is continuous with the endothelial lining of the blood vessels (arteries and veins) connected to the heart, ensuring a smooth transition for blood entering and exiting the heart.
Jan 4, 2024 · Endocardium. The innermost layer of the cardiac wall is known as the endocardium. It lines the cavities and valves of the heart.. Structurally, the endocardium is comprised of loose connective tissue and simple squamous epithelial tissue – it is similar in its composition to the endothelium which lines the inside of blood vessels.

The pericardium has 2 layers---a visceral layer that covers the outside of the heart and a parietal layer that forms a sac around the outside of the pericardial cavity. Structure of the Heart Wall. The heart wall is made of 3 layers: epicardium, myocardium and endocardium. Epicardium. The epicardium is the outermost layer of the heart wall and ...

Oct 30, 2023 · The heart contains three basic layers similar to those seen in arteries and veins. The outermost layer is the epicardium, which is derived from the proepicardium (from the septum transversum). The middle layer is the myocardium, and the innermost layer is the endocardium, which originated from mesothelial cells of the outflow tract.
