Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Ear Muscles & Vermiform appendix
Concept:

Vestigial organs are physical remnants of structures that had important functions in our evolutionary ancestors but have lost their primary purpose in modern humans.

Solution:

  • Vermiform appendix: A shrunken remnant of a larger cecum used by our distant herbivorous ancestors to digest tough plant matter.
  • Ear Muscles (auricular muscles): In many mammals (like dogs and horses), these muscles pivot the ears to localize sound. In humans, they are largely non-functional.
  • Therefore, Ear Muscles & Vermiform appendix is the correct pair of vestigial organs.


Why other options are incorrect:

  • The Heart and Liver are highly active, vital organs essential for immediate human survival; they are definitively not vestigial.

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.
