Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Gastrin
Concept:

Gastric secretion is tightly regulated by both neural and hormonal mechanisms triggered by the presence of food.

Formula:

N/A

Solution:

  • When protein-rich food enters the stomach, specific G-cells in the gastric mucosa are stimulated to release the hormone Gastrin into the bloodstream.
  • Gastrin circulates back to the stomach wall, potently stimulating parietal cells to release HCl and chief cells to release pepsinogen, thereby ramping up digestive activity.


Why other options are incorrect:

Secretin and Cholecystokinin (CCK) are intestinal hormones that primarily stimulate the pancreas and gallbladder while inhibiting stomach activity. Acetylcholine is a neurotransmitter, not a hormone.

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.
