Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Ventricles
Concept:

Chordae tendineae are the physical tension cords that anchor the atrioventricular (AV) valves during systolic contraction.

Formula:

None

Solution:

  • During ventricular contraction, pressure spikes rapidly, threatening to blow the AV valves backward into the atria.


  • Chordae tendineae connect the valve flaps to papillary muscles that sprout from the inner walls of the ventricles.


  • Therefore, these structures are anatomically housed entirely within the left and right ventricles.


Why other options are incorrect:

  • Atria: Have smooth or pectinate muscle, but no chordae tendineae.


  • Aortic/Pulmonary valves: Are semilunar valves and do not require chordae tendineae to function.

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.
