Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Lacunae
Concept:

Microscopic anatomy of cartilage.

Formula:

N/A (Conceptual)

Solution:

  • Because the extracellular matrix of cartilage is extremely dense and rubbery, the resident cells (chondrocytes) cannot freely float.


  • Instead, they are permanently trapped within tiny, fluid-filled hollow spaces or 'little lakes' distributed throughout the matrix. These specific cavities are called Lacunae.


Why other options are incorrect:

The perichondrium is the outer fibrous membrane wrapping the whole cartilage. The periosteum wraps bone. The shaft refers to the diaphysis of a long bone.

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.
