Multiple Choice

The outer layer of the serous pericardium is called which?

Parietal layer of the serous pericardium lines the fibrous pericardium, forming the outer boundary. The visceral layer (epicardium) covers the heart itself and is continuous with the parietal layer at the great vessels, with a lubricated pericardial cavity between them. Endocardium lines the interior of the heart chambers, and myocardium is the heart muscle. So the outer layer of the serous pericardium is the parietal layer.
