the heart. The three layers encircle the ventricles and re-attach
at different points along the fibrous skeleton of the heart.
The musculature of the heart consists of separate but
interdigitated layers of cardiac muscle tissue. The cardiac
muscles all attach to the fibrous skeleton at the base of
the heart. The three layers encircle the ventricles and re-attach
at different points along the fibrous skeleton of the heart.
