Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Acetylcholine
Concept:

Different neurotransmitters dominate different divisions of the nervous system.

Solution:

  • Outside the CNS, within the Peripheral Nervous System (specifically at the neuromuscular junction and in autonomic ganglia), Acetylcholine (ACh) is the primary active neurotransmitter responsible for stimulating skeletal muscles and parasympathetic responses.


Why other options are incorrect:

  • Dopamine: Primarily active within the brain (CNS).


  • Androgen: A steroid hormone, not a neurotransmitter.


  • Polypeptide: A broad category of molecules, not specific.

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.
