The right fibrous ring is known as the annulus fibrosus dexter cordis, and the left is known as the annulus fibrosus sinister cordis. [3] The right fibrous trigone is continuous with the central fibrous body. This is the strongest part of the fibrous cardiac skeleton.
The four cardiac valves are kept in their place partly because of the fibrous skeleton of the heart, which is a collection of connective tissue. It consists of the right fibrous trigone (which along with the membranous septum forms the central fibrous body), the left right fibrous trigone, and the conus tendon. The right fibrous trigone is the ...
Cardiac fibrosis is common in non-human great apes in human care. The term idiopathic myocardial fibrosis was coined to emphasize this disease is likely different from the above described forms of cardiac fibrosis in humans. The etiology is not known, though vitamin D deficiency is a potential suspected cause at least in chimpanzees. [31]
The fibrous cardiac skeleton gives structure to the heart. It forms the atrioventricular septum, which separates the atria from the ventricles, and the fibrous rings, which serve as bases for the four heart valves. [21]
The cardiac conduction system (CCS, ... There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG.
The chordae tendineae (sg.: chorda tendinea) or tendinous cords, colloquially known as the heart strings, are inelastic cords of fibrous connective tissue that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
Heart valves are situated around the fibrous rings of the cardiac skeleton. The valves incorporate flaps called leaflets or cusps, similar to a duckbill valve or flutter valve, which are pushed open to allow blood flow and which then close together to seal and prevent backflow. The mitral valve has two cusps, whereas the others have three ...
Myocardial scarring is the accumulation of fibrous tissue resulting after some form of trauma to the cardiac tissue. [ 1 ] [ 2 ] Fibrosis is the formation of excess tissue in replacement of necrotic or extensively damaged tissue.
