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.
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.

A cardiac skeleton anchors the four heart valves and the atria and ventricles. The thick wall separating the two ventricles, the interventricular septum, houses the Purkinje fibers, which play an important part in the electrical activity of the heart ( Murphy and Lloyd, 2007 ).
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 · 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.

Jun 21, 2019 · Summary. Cardiac muscle tissue, or myocardium, is a type of muscle tissue that forms the heart. Cardiac muscle tissue contracts and releases involuntarily. It is responsible for keeping the...
Oct 20, 2024 · The myocardium is built upon a framework of dense connective tissue called the cardiac skeleton (covered in detail later in this section). It is the contraction of the myocardium that pumps blood through the heart and into the major arteries.
