Lacks vascular supply
B
Lacks minerals deposits in matrix
C
Has less number of cells deep down
D
Lacks protein in matrix

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Lacks vascular supply
Concept:

Tissue regeneration dependencies.

Formula:

N/A (Conceptual)

Solution:

  • Tissue healing relies strictly on the rapid delivery of immune cells, oxygen, and nutrients to the site of damage.


  • Unlike highly vascularized bone, cartilage is essentially avascular (lacks direct blood vessels).


  • Consequently, repair materials must slowly percolate through the dense matrix via diffusion, making cartilage healing notoriously sluggish or completely ineffective.


Why other options are incorrect:

Cartilage contains abundant proteins (collagen/elastin). While it lacks mineral deposits (calcium), that factor contributes to its flexibility, not its inability to heal.

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.
