The right and left fibrous rings of heart (annuli fibrosi cordis) surround the atrioventricular and arterial orifices. 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.
It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It is anatomically significant because the atrioventricular node is located at the apex of the triangle. The ...
The right fibrous trigone is the strongest part of the skeleton. It lies to the right of the aortic valve and connects it with the mitral and tricuspid valves. It is pierced by the bundle of His. Lastly, the aortomitral curtain is also a part of the fibrous skeleton; it is formed by fibrous tissue connecting two of three of the aortic valve ...
The right fibrous trigone is continuous with the central fibrous body. This is the strongest part of the fibrous cardiac skeleton . Does that indicate: The right trigone is the strongest part of cardiac skeleton - or - Fibrous rings are strongest part of cardiac skeleton ? Kurosh 16:17, 3 September 2024 (UTC)
The bundle of His (BH) [1]: 58 or His bundle (HB) [1]: 232 (/ h ɪ s / "hiss" [2]) is a collection of heart muscle cells specialized for electrical conduction.As part of the electrical conduction system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the apex of the fascicular branches via the ...
The primary functions of the TFCC: To cover the ulna head by extending the articular surface of the distal radius. Load transmission across the ulnocarpal joint and partially load absorbing; Allows forearm rotation by giving a strong but flexible connection between the distal radius and ulna. It also supports the ulnar portion of the carpus.
In four hearts, a single, hyperdense structure was detected within the right fibrous trigone of the cardiac skeleton. High resolution scans and histopathology revealed trabecular bones in two cases, hyaline cartilage in another case and a focus of mineralised fibro-cartilaginous metaplasia with endochondral ossification in the last case.
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.
