Uberon definition : Dense connective tissue that separates the atria from the ventricles and provides
physical support for the heart.;
Uberon synonym : cardiac fibrous skeleton; skeleton of heart; fibrous skeleton of heart; heart fibrous skeleton;
Uberon Function note : It is not a true skeleton, but it does provide structure and support for the heart,
as well as isolating the atria from the ventricles. This allows the AV node and AV
bundle to delay the wave of depolarisation such that the atria can contract and assist
in ventricular filling before the ventricles themselves depolarise and contract (the
AV bundle is the only part of the conduction system that passes from the atria to
the ventricles in a normal heart). It also allows the valves (bicuspid, tricuspid,
semilunar) to keep open by giving them structural support[WP];
