- 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.

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.
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.
Jan 2, 2023 · The base of the heart contains a highly dense structure known as the fibrous or cardiac skeleton. Functions of the fibrous skeleton include providing a strong framework for cardiomyocytes, anchoring the valvular leaflets, and acting as electrical insulation separating the conduction in the atria and ventricles.

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.

Mar 28, 2024 · Like the human body, the heart has its skeleton. The 4 chambers of the heart are attached to it. There are 4 rigid fibrous rings and a tiny vertical section a few millimeters long in the lower center. This marks the beginning of the septum separating the 2 ventricles.
These sheets of cells are anchored to the fibrous skeleton of the heart, which surrounds the atrioventricular valves and the origins of the aorta and pulmonary artery. The myocardial thickness is related to the pressure present in each chamber; thus the atria are thin walled and the ventricles are thicker.
