Question

Please I need help understanding this question, I'm not sure if I'm understanding it right. 

**Question:** The cusps (leaflets) of atrioventricular valves attach directly to - ○ trabeculae carneae. - ○ interatrial septa. - ○ papillary muscles. - ● chordae tendineae. - ○ coronary sulci. **Explanation:** This is a multiple-choice question regarding the attachment of the cusps (leaflets) of atrioventricular valves. The correct answer is "chordae tendineae," which are fibrous cords that connect the valve cusps to papillary muscles within the ventricles. This structure helps prevent valve prolapse during the contraction of the heart.
