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]
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) between them. [1]
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 ...
Pericardial fluid. 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. Pericardial fluid is the serous fluid secreted by the serous layer ...
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 pericardium is present in order to lubricate its movement against other structures within the chest, to keep the heart's position stabilised ...
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 pericardium is a fibrous sac surrounding the heart composed of two layers: an inner visceral pericardium and an outer parietal pericardium. [1] The area between these two layers is known as the pericardial space and normally contains 15 to 50 mL of serous fluid. [2] This fluid protects the heart by serving as a shock absorber and provides ...
Cardiac skeleton. In cardiology, the cardiac skeleton, also known as the fibrous skeleton of the heart, is a high-density homogeneous structure of connective tissue that forms and anchors the valves of the heart, and influences the forces exerted by and through them. The cardiac skeleton separates and partitions the atria (the smaller, upper ...
