Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Skeletal muscles
Concept:

Muscle tissue classification by control mechanism.

Formula:

N/A (Conceptual)

Solution:

  • Voluntary muscles are those that can be consciously controlled by the somatic nervous system.


  • Skeletal muscles are attached to the skeleton and are responsible for all conscious movements (walking, lifting, etc.), making them strictly voluntary.


Why other options are incorrect:

Cardiac muscle (heart) and Smooth muscle (digestive tract, blood vessels) are controlled by the autonomic nervous system and are entirely involuntary.

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.
