What are the layers of the pericardium
Fibrous pericardium Serous pericardium (parietal layer and visceral layer)
The pericardium is a fluid-filled sac that surrounds and protects the heart. It consists of two main layers:
1. Fibrous pericardium: This is the outermost layer of the pericardium and is made up of tough connective tissue. Its main function is to protect the heart from physical damage and prevent it from over-distending.
2. Serous pericardium: This is a double-layered membrane that is located inside the fibrous pericardium. The two layers of the serous pericardium are:
– Parietal layer: This is the outer layer of the serous pericardium that lines the inner surface of the fibrous pericardium.
– Visceral layer (also called the epicardium): This is the inner layer of the serous pericardium that covers the surface of the heart.
Between the parietal and visceral layers of the serous pericardium, there is a small space called the pericardial cavity. This space is filled with a small amount of fluid that acts as a cushion and reduces friction as the heart beats.
