Pericardial cavity

Pericardial cavity is a potential space between the parietal pericardium and the serous layer of the visceral pericardium, which is also known as the epicardium. It is a part of the mediastinum and is located between the sternum and the vertebral column. The pericardial cavity is filled with pericardial fluid which provides lubrication for the movement of the heart.

Structure

The pericardial cavity is a thin space which is located between the parietal and visceral layers of the pericardium. The parietal pericardium is a fibrous layer which attaches to the sternum and the diaphragm, and the visceral pericardium is a serous layer which is directly attached to the heart. The space between these two layers is filled with pericardial fluid.

Function

The main function of the pericardial cavity is to provide lubrication for the heart. The pericardial fluid within the cavity reduces friction between the layers of the pericardium as the heart beats. This allows the heart to move freely within the chest cavity.

Clinical significance

Conditions that can affect the pericardial cavity include pericarditis, which is inflammation of the pericardium, and pericardial effusion, which is an abnormal accumulation of fluid in the pericardial cavity. These conditions can cause chest pain and other symptoms, and may require medical treatment.
