Which two valves have chordae tendineae and papillary muscles attached?

Explanation:
Chordae tendineae and papillary muscles form part of the atrioventricular valve mechanism, preventing the valve leaflets from flipping into the atria when the ventricles contract. The two AV valves—the tricuspid on the right and the mitral (bicuspid) on the left—have these structures attached. The semilunar valves (aortic and pulmonary) lack chordae tendineae and papillary muscles; their cusps are supported differently and closed by pressure rather than by tethered leaflets. So the valves with chordae tendineae and papillary muscles are the tricuspid and bicuspid.
