Visceral Layer Of Serous Pericardium
The Pericardium
The pericardium is the gristly sac that surrounds the middle. Information technology can exist divided into iii layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium. The two layers of the serous pericardium are continuous with each other.
The fibrous pericardium is a layer of connective tissue that provides support and protection for the heart. It has a number of attachments to the diaphragm, the sternum (via the sterno-pericardial ligaments), and the vertebral column. It holds the heart in place.
The inner surface of the fibrous pericardium is lined past the outer (parietal) layer of serous pericardium. The inner (visceral) layer of the serous pericardium lines the outer surface of the heart itself. Betwixt the two layers of the serous pericardium is the pericardial cavity, which contains pericardial fluid. It is this fluid that provides lubrication between the ii layers, and allows the heart to aggrandize and contract.
The classic pic of the way in which the serous pericardium works is if y'all push button your fist into a balloon. The layer of prophylactic covering your mitt is coordinating with the visceral layer, the within of the balloon is coordinating to the pericardial cavity, and the outer layer of the airship non in contact with your mitt is equivalent to the parietal pericardium.
Pericarditis is an inflammation of the serous pericardium of the heart. It results in an accumulation of fluid in the pericardial cavity, which effects the pattern of beating in the heart.
A massively increased amount of fluid in the pericardial crenel will result in the center not being able to fill properly, meaning information technology will be unable to propel claret around the torso in its normal fashion. This status is called cardiac tamponade, and volition frequently require the gristly pericardium to be surgically opened in order to remove the backlog fluid.
