- The fibrous skeleton separates the atrial musculature from that of the ventricles. It serves as the framework for the attachment of myocardial fibers, with atrial fibers arising from the upper border of the rings and ventricular fibers originating from the lower border of the rings.

Jan 2, 2023 · As the fibers travel inferiorly, they penetrate the central fibrous body of the cardiac skeleton to form the bundle of His. These fibers are the Purkinje fibers after they divide within the interventricular septum and branch into the ventricles.

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, or fibrous skeleton of the heart, is the structure of dense connective tissue that separates the atria from the ventricles. The fibrous skeleton provides critical support for the heart and separates the flow of electrical impulses through the heart.
Connective tissue fibers form a dense network called the fibrous cardiac skeleton that reinforces the myocardium and anchors cardiac muscle fibers. Without this additional support, the vessels and valves might eventually become stretched because of the continuous stress of blood pumping through them.
The structure of the heart and muscular fibers are set around a fibrous cardiac skeleton consisting of dense connective tissue. The bulk of the fibrous skeleton consists of four fibrous rings that surround the orifices of the valves.
Aug 18, 2017 · The fibrous skeleton is concentrated at the base of the ventricular mass. It provides electrical insulation at the atrioventricular level and fibrous continuity for the leaflets of the mitral, aortic, and tricuspid valves.
