The flaps of tricuspid valve are attached to papillary muscles of the wall of right ventricle by means of:
Correct answer: B. Fibrous cords called chordae tendineae
- A. Fibrous cords
- B. Fibrous cords called chordae tendineae
- C. Fibrous cords called ligaments
- D. Epithelial extensions
Explanation
The flaps (cusps or leaflets) of the tricuspid valve are attached to the papillary muscles of the right ventricle by means of chordae tendineae. Chordae tendineae are strong, fibrous cords that extend from the papillary muscles to the edges of the tricuspid valve's three cusps. These tendinous cords play a critical role in stabilizing the tricuspid valve during ventricular contraction (systole).

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
