Study Notes

Pericardium Structure

The serous pericardium consists of two layers: the parietal layer and the visceral layer (also known as the epicardium).
The parietal layer lines the inner surface of the fibrous pericardium.
The visceral layer forms the epicardium, which is the outermost layer of the heart wall.
The fibrous pericardium is attached to the central tendon of the diaphragm by the pericardiophrenic ligament.

Pericardial Cavity

The pericardial cavity is located between the parietal and visceral layers of the serous pericardium.
The pericardial cavity is filled with a small amount of fluid that lubricates the movement of the heart.

Fibrous Pericardium

The fibrous pericardium is attached to the sternum by the sternopericardial ligaments.
The fibrous pericardium is composed of dense connective tissue.

Serous Pericardium Composition

The serous pericardium is composed of a thin layer of mesothelial cells and a layer of loose connective tissue.

Function

The pericardiophrenic ligament helps to anchor the heart to the diaphragm.
The pericardial cavity allows for frictionless movement of the heart during contractions.
