Question

Mitral valve and tricuspid valve are attached to the papillary muscles by

• A. Corpus callosum
• B. Columnae carnae
• C. Crura cerebri
• D. Chordae tendinae

Answer 1

The correct option is D Chordae tendinae

• Chordae tendineae are tendinous cords that are fibrous in nature. It plays a vital role in connecting the mitral valve and tricuspid valve to the papillary muscles in the heart.
• It holds tricuspid (atrioventricular) valves in its place when heart is pumping the blood.
• Due to the attachment of valves to papillary muscles, contraction of papillary muscles open the valves and relaxation of papillary muscles close the valves.

Thus, the correct answer is option D.
