What is the inner layer of the heart wall called?

  1. Myocardium

  2. Visceral layer

  3. Epicardium

  4. Endocardium

The correct answer is: Endocardium

The inner layer of the heart wall is called the endocardium. This layer lines the heart chambers and covers the heart valves, providing a smooth, frictionless surface that facilitates the flow of blood through the heart. The endocardium is composed of a thin layer of endothelial cells, connective tissue, and a layer that contains small blood vessels and nerves, which are crucial for the heart's overall function and health. Understanding the structure and function of the endocardium is important in echocardiography because any abnormalities or diseases affecting this layer can influence cardiac function and may be visualized during an echocardiogram. Conditions such as endocarditis, which is an infection of the endocardium, can lead to significant complications and are often assessed through echocardiography to evaluate the state of the heart valves and chambers.
