Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Brain
Concept:

Endogenous pain regulation originates centrally within the nervous system.

Solution:

  • Endorphins are naturally occurring opioid peptides synthesized primarily in the pituitary gland and the hypothalamus within the brain in response to pain or stress.


Why other options are incorrect:

  • Adrenal gland: Produces stress hormones like cortisol and adrenaline.


  • Stomach / Thymus: Involved in digestion and immunity, respectively, not endogenous analgesia.

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.
