Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Osteocytes
Concept:

Anatomy of the Haversian system.

Formula:

N/A (Conceptual)

Solution:

  • Once active osteoblasts secrete enough matrix to completely surround and trap themselves, the matrix calcifies and hardens.


  • The trapped cells mature into Osteocytes, which permanently reside inside these tiny bony chambers known as lacunae. They maintain local bone metabolism.


Why other options are incorrect:

Chondrocytes reside in the lacunae of cartilage, not bone. Osteoblasts and osteoclasts operate directly on the outer surfaces of the bone tissue, not inside trapped internal lacunae.

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.
