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. Below the mesothelial cells is a layer of adipose and connective tissue that binds the epicardium to ...

Aug 4, 2023 · 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. Epicardium encloses the heart as well as the root of major blood vessels emerging from the heart like the aorta and the two ...

- 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.
Oct 20, 2024 · The slight deviation of the apex to the left is reflected in a depression in the medial surface of the inferior lobe of the left lung, called the cardiac notch. Figure 17.2.1 17.2. 1: Location of Heart in the Thorax. The heart is located within the thoracic cavity, medially between the lungs in the mediastinum.
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.
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.

Layers. The wall of the heart is composed of three layers of unequal thickness. From superficial to deep, these are the epicardium, the myocardium, and the endocardium (see Figure 19.1.3). The outermost layer of the wall of the heart is also the innermost layer of the pericardium, the epicardium, or the visceral pericardium discussed earlier.
