Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: 12 pairs
Concept:

Nerves are always organized bilaterally (in symmetrical left-right pairs) as they exit the central nervous system.

Solution:

  • There are exactly 12 pairs of cranial nerves emerging directly from the brain/brainstem to innervate primarily the head and neck.


Why other options are incorrect:

  • 31 pairs: Represents the number of spinal nerves exiting the spinal cord.


  • 24 pairs / 62 pairs: Anatomically incorrect groupings.

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.
