Fibrous pericardium

From Wikipedia, the free encyclopedia

Fibrous 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 fibrosum
Dorlands/Elsevier	p_12/12626527

The fibrous pericardium is the most superficial layer of the pericardium. It is a dense connective tissue, protecting the heart, anchoring it to the surrounding walls, and preventing it from overfilling with blood. It is continuous with the outer adventitial layer of the neighboring great blood vessels.
