Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Brain
Concept:

Endorphins are endogenous opioid neuropeptides that act as natural analgesics (painkillers).

Solution:

  • Endorphins are primarily synthesized and stored within the central nervous system, specifically in the pituitary gland and the hypothalamus of the brain.


  • They are released in response to pain, stress, or intense physical exercise (causing "runner's high").


Why other options are incorrect:

The adrenal gland handles adrenaline and cortisol. The thymus manages T-cell maturation, and the stomach secretes digestive juices.

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.
