Cardiac skeleton

From Wikipedia, the free encyclopedia

Cardiac skeleton (sometimes called "fibrous skeleton of the heart") refers to the structure of dense connective tissue in the heart that separates the atria from the ventricles.

It is not a "true" skeleton, but it does provide structure and support for the heart, as well as isolating the electric charges that go through the heart.

v • d • e Anatomy of torso, cardiovascular system: heart

Structures	atria (interatrial septum, musculi pectinati) • ventricles (interventricular septum, trabeculae carneae, chordae tendinae, papillary muscle) • valves • cusps

Regions	base • apex • grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) • surfaces (sternocostal, diaphragmatic) • borders (right, left)

Right heart	(vena cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of the inferior vena cava, valve of the coronary sinus) → tricuspid valve → right ventricle (conus arteriosus, moderator band/septomarginal trabecula) → pulmonary valve → (pulmonary artery and pulmonary circulation)

Left heart	(pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)

Layers	pericardium: fibrous pericardium • serous pericardium (pericardial cavity, epicardium/visceral layer) • pericardial sinus myocardium • endocardium • cardiac skeleton (fibrous trigone, fibrous rings)

Conduction system	Cardiac pacemaker • SA node • AV node• bundle of His • Purkinje fibers
