Oct 30, 2023 · The fibrous skeleton of the heart, also called the cardiac skeleton, consists of four fibrous rings (anuli fibrosi, singular: annulus fibrosis) and the membranous portions of the septa of the heart. This skeleton is located at the base of the ventricles, between the atria and the ventricles.

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.
Jan 2, 2023 · Histologically, the heart is mainly composed of cardiomyocytes and connective tissue. Dense 2 connective tissue with elastic fibers is in the cardiac/fibrous skeleton. Certain stains, such as Masson's elastic trichrome stains, can help visualize these components.

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.
Aug 18, 2017 · This review provides a comprehensive overview of the anatomy of the fibrous skeleton of the heart and its related components, supported by relevant images of anatomy and pathologic processes. The fibrous skeleton is concentrated at the base of the ventricular mass.

The pericardium, which literally translates as “around the heart,” consists of two distinct sublayers: the sturdy outer fibrous pericardium and the inner serous pericardium. The fibrous pericardium is made of tough, dense connective tissue that protects the heart and maintains its position in the thorax.

The fibrous skeleton of the human heart is composed of several parts which are formed from different, mainly extracardiac sources. The atrioventricular valve rings are formed by invagination of sulcus tissue at the atrioventricular and bulboventricular transitions.
