Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Ventricle
Concept:

Chordae tendineae are the mechanical anchors for the atrioventricular valves.

Formula:

None

Solution:

  • These tendinous cords extend from the inferior edges of the AV valve cusps downwards.


  • They attach to the papillary muscles, which are specialized extensions of the ventricular walls. Therefore, they are physically located within the ventricles.


Why other options are incorrect:

  • Atria: Receive blood; do not contain chordae tendineae.


  • Pulmonary valve: A semilunar valve, which relies on its cup-like shape to close, lacking chordae tendineae entirely.

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.
