Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Corpus luteum
Concept:

Follicle morphology changes dramatically once the oocyte is expelled.

Solution:

  • Once the mature (vesicular or Graafian) follicle ruptures and releases the egg, the remaining granulosa and theca cells collapse inward.


  • Under the influence of Luteinizing Hormone (LH), these cells accumulate a yellow pigment called lutein.


  • This newly formed, fatty, yellow glandular mass is anatomically termed the corpus luteum.


Why other options are incorrect:

"Graafian luteum" is a mixed, fabricated term. A ruptured ovum refers to the egg itself, not the follicle. It is no longer just a standard "follicle" once luteinized.

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.
