Nov 3, 2023 · The epicardium is the outermost layer of the heart. It is actually the visceral layer of the serous pericardium, which adheres to the myocardium of the heart. Histologically, it is made of mesothelial cells, the same as the parietal pericardium.

- 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 · The endocardium is the innermost layer of the heart wall lining the internal chambers of the heart and the heart valves. It provides a smooth surface for efficient blood flow inside the heart chambers. It also houses capillaries to supply blood to the heart muscles, nerve fibers, and heart conduction cells.
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.
The heart wall is comprised of three layers, the epicardium (outer), myocardium (middle), and endocardium (inner). These tissue layers are highly specialized and perform different functions.
Oct 31, 2024 · The heart consists of several layers of a tough muscular wall, the myocardium. A thin layer of tissue , the pericardium , covers the outside, and another layer, the endocardium , lines the inside. The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers .
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.
