  1. 19 sty 2022 · The epicardium is composed of mesothelium, a cell type that covers and protects most of the internal organs of the body as well as fat and connective tissue. The epicardium predominantly surrounds the heart and the roots of the coronary vessels emerging from it, including the aorta, the superior vena cava, and inferior vena cava.

  2. 26 lip 2024 · The epicardium is composed primarily of loose connective tissue, including elastic fibers and adipose tissue. The epicardium functions to protect the inner heart layers and also assists in the production of pericardial fluid.

  3. The epicardium is a mesothelium forming the outermost layer of the heart. Epicardial cells arise from an extracardiac embryonic tissue (the proepicardium), migrate towards the developing heart and envelop the myocardium.

  4. 3 lis 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.

  5. 20 paź 2024 · The endocardium lines the chambers where the blood circulates and covers the heart valves. It is made of simple squamous epithelium called endothelium, which is continuous with the endothelial lining of the blood vessels (Figure \(\PageIndex{4}\)).

  6. The heart is lined by a single layer of mesothelial cells called the epicardium that provides important cellular contributions for embryonic heart formation.

  7. The epicardium is a layer of epithelial cells that wrap the whole heart. This layer mainly contributes to generate smooth muscle cells and cardiac fibroblasts (Lie-Venema et al., 2007). What's more, the epicardium is closely related to proliferation of cardiomyocytes and maintains the compact myocardium (Merki et al., 2005).
