Question

Quizplus · Accepted Answer

The epicardium is also known as the visceral layer of the serous pericardium as it is the outermost layer of the heart wall that is in contact with the pericardial cavity. The myocardium is the middle layer of the heart wall that contains cardiac muscle cells, the endocardium is the innermost layer of the heart wall that lines the chambers and heart valves, and the parietal layer of the serous pericardium is the outer layer of the pericardium that lines the inner surface of the fibrous pericardium. Therefore, neither the endocardium nor the parietal layer of the serous pericardium are synonymous with the visceral layer of the serous pericardium.
