Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Tricuspid valve of heart
Concept:

Valvular prolapse in the heart is prevented by tension cables.

Formula:

None

Solution:

  • Chordae tendineae (heart strings) are tough, tendinous cords in the heart.


  • They connect the papillary muscles to the tricuspid valve (and bicuspid valve) to prevent them from inverting during ventricular systole.


Why other options are incorrect:

  • Options A, B, and D describe structures completely unrelated to cardiovascular anatomy.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
