The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium). [2][3] It encloses the ...
The pericardium is a thick membrane that covers the heart. It consists of two layers: the fibrous pericardium and the serous pericardium. It forms two recesses: the transverse recess and oblique recess. The transverse recess lies behind the aorta and pulmonary trunk, while the oblique recess lies behind the left atrium. [5]
The pericardiacophrenic arteries travel through the thoracic cavity. They course through the fibrous pericardium. [2] The pericardiacophrenic artery accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm. [3] This is where both the artery and the phrenic nerve are distributed.
This is lined by a double inner membrane called the serous membrane that produces pericardial fluid to lubricate the surface of the heart. [30] The part of the serous membrane attached to the fibrous membrane is called the parietal pericardium, while the part of the serous membrane attached to the heart is known as the visceral pericardium.

The fibrous pericardium is attached to the posterior surface of the sternum by the superior and inferior sternopericardiac ligaments ...
Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart. [ 8 ] Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. [ 1 ] The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. [ 1 ]
The "swinging" heart. A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space ...
The pericardium, the double-walled sac surrounding the heart, consists of a fibrous pericardium layer on the outside and a double-layered serous pericardium on the inside. [18] Between the two layers of the serous pericardium is the pericardial space, which is filled with lubricating serous fluid that prevents friction as the heart contracts. [19]
