Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Nissl's Granules
Concept:

Neuroanatomists name specific cellular structures based on historical staining techniques.

Solution:

  • When stained with basic dyes, the neuronal cell body shows prominent basophilic clumps. These clumps, discovered by Franz Nissl, are known as Nissl's Granules. They are structurally comprised of densely packed rough endoplasmic reticulum and free ribosomes used for high-capacity protein production.


Why other options are incorrect:

  • Soma: The entire cell body itself, not the specific organelles inside it.


  • Neuroglia: The entire class of supporting cells (like astrocytes), not an organelle.


  • Axofibrils: Cytoskeletal structures (neurofibrils) in the axon for transport, not protein synthesis.

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.
