26 lip 2024 · The three heart wall is divided into three layers: epicardium, myocardium, and endocardium. Epicardium: the outer protective layer of the heart. Myocardium: muscular middle layer wall of the heart. Endocardium: the inner layer of the heart.
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.
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 \(\PageIndex{4}\)).
30 paź 2023 · The visceral portion (that is in contact with the heart) is called the epicardium. It is a mesothelium derivative that is rich in adipocytes and neurovascular tissue. This layer is well lubricated, which facilitates smooth movement of the heart against the parietal pericardium during contraction.
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 (see Figure 6.1.4).
The epicardium consists of a simple squamous epithelium called a mesothelium, reinforced with loose, irregular, or areolar connective tissue that attaches to the pericardium. This mesothelium secretes the lubricating serous fluid that fills the pericardial cavity and reduces friction as the heart contracts.
