The cardiac skeleton also known as the fibrous skeleton of the heart is a high density single structure of connective tissue that forms and anchors the valves and influences the forces exerted through them. The cardiac skeleton separates and partitions the atria (the smaller upper two chambers) from the ventricles (the larger lower two chambers). This is important because it forms the primary channel that electrical energy follows from the top to the bottom of the heart.
