Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Mucus cells secrete mucin
Concept:

The gastric gland features a precise division of labor among its cell types to produce the components of gastric juice without digesting the stomach itself.

Formula:

N/A

Solution:

  • Mucus cells (or mucous neck cells) are located in the upper part of the gland and continuously synthesize and secrete mucin.
  • Mucin mixes with water to form a thick, alkaline mucus barrier that protects the stomach lining from its own acid and proteases.


Why other options are incorrect:

Chief cells secrete pepsinogen (not gastrin). Hormone (G) cells secrete gastrin (not intrinsic factor). Parietal cells secrete HCl and intrinsic factor (not pepsinogen).
