Study Notes
Coverings of the Heart
- The heart is enclosed in a double-walled sac called the pericardium.
- The fibrous pericardium is the superficial, tough, dense connective tissue layer that protects the heart, anchors it to surrounding structures, and prevents overfilling.
- The serous pericardium is deep to the fibrous pericardium and is a thin, slippery, two-layer membrane.
- The parietal layer of the serous pericardium lines the internal surface of the fibrous pericardium.
- The visceral layer, also known as the epicardium, is the part of the serous pericardium that continues over the external surface of the heart's wall.
- The slit-like pericardial cavity is between the parietal and visceral layers and contains serous fluid that lubricates the membranes and allows smooth movement during heart activity.
