Serous pericardium



Serous pericardium
A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart.
Latin pericardium serosum
Dorlands/Elsevier p_12/12626540

The serous pericardium is deeper than the fibrous pericardium. It contains two layers, both of which function in lubricating the heart to prevent friction from occurring during heart activity:

  • The layer next to the fibrous pericardium is the parietal layer.
  • The layer deep to the fibrous pericardium is the visceral layer.[1] When this layer comes into contact with the heart (not the great vessels), it is known as the epicardium.

Additional recommended knowledge

Together these two layers form a continuous uninterrupted membrane. Between these two layers exists a small cavity called the pericardial cavity, which contains a supply of serous fluid. The serous fluid that is found in this space is known as the pericardial fluid.
