Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: One
Concept:

Histological structure of smooth muscle cells.

Formula:

N/A (Conceptual)

Solution:

  • Smooth muscle cells are involuntary, non-striated, and characteristically spindle-shaped.


  • Unlike skeletal muscle, each individual smooth muscle cell contains only a single, centrally located nucleus (they are uninucleate).


Why other options are incorrect:

Skeletal muscle cells form from the fusion of many myoblasts, resulting in long, multinucleated syncytia. Smooth muscles do not undergo this fusion.

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.
