Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Uni-nucleate
Concept:

Histological characteristics of smooth muscle.

Formula:

N/A (Conceptual)

Solution:

  • Smooth muscle cells line internal organs (like the gut and blood vessels) and act entirely involuntarily.


  • Under a microscope, they appear as isolated, non-striated, spindle-shaped cells. Unlike fused skeletal fibers, each individual smooth muscle cell possesses exactly one central nucleus, making them definitively Uni-nucleate.


Why other options are incorrect:

They are strictly involuntary (not voluntary). They are spindle-shaped (not branched like cardiac cells). They lack sarcomeres entirely, meaning they have no striated appearance.

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.
