Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Trachea
Concept: The human respiratory tract is lined with ciliated epithelium interspersed with specialized secretory cells to protect the delicate alveolar surfaces.

Solution:
  • Goblet cells are unicellular glands that secrete mucus.
  • In the respiratory system, they are abundantly present in the lining of the trachea and bronchi.
  • The secreted mucus traps incoming dust, microbes, and foreign particles, which are then swept upward by cilia.


Why other options are incorrect:
  • Larynx, Glottis, Epiglottis: These structures are primarily cartilaginous and are involved in sound production and preventing food from entering the airway. While they have mucosal linings, the trachea is the classical primary site known for its rich distribution of goblet cells for air filtration.

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.
