The inner surface of the left ventricle is covered with muscular ridges, trabeculae carne, like those of the right ventricle [trabeculae carneae in right ventricle].
In the left ventricle, identify the thin strands which resemble the chordae tendineae. These strands, however, do not attach to the cusps of the mitral valve; they contain Purkinje fibers and are called false chordae tendineae. They are components of the conduction system of the heart.
