Nov 3, 2023 · 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.

- 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.
Aug 4, 2023 · Interesting Science Videos. 1. Epicardium (Outermost Layer of Heart) The epicardium is the outermost layer of the heart wall made up of mesothelium, fats, and connective tissues. It forms the inner serous layer of the pericardium; hence, it is also known as the visceral serous pericardium.
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.
Jan 4, 2024 · 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.

Jun 9, 2024 · The endothelium is the innermost layer, which controls the exchange of any materials between the bloodstream and the heart muscles. It consists of specialized endothelial cells, which are the same type found lining the arteries and veins.
Mar 2, 2024 · The endocardium is the innermost lining layer of the heart, which covers the internal surfaces of the heart chambers and valves. It is one of the three main layers of the heart wall, the other two being the myocardium (the muscular middle layer) and the epicardium (the outer layer).
