What structures anchor the chordae tendineae?

Question

Quizplus · Accepted Answer

Papillary muscles are small, conical muscles located in the walls of the ventricles of the heart. They are responsible for anchoring the chordae tendineae, which attach to the valve cusps, preventing them from being inverted into the atria during ventricular contraction. Trabeculae carneae are muscular ridges on the internal surface of the ventricular walls, pectinate muscles are muscular ridges in the atria, and semilunar valves are the valves that prevent blood from flowing back into the ventricles.
