Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Reflex arc
Concept:

Anatomical structures create the specific "wiring" for physiological behaviors.

Solution:

  • The actual anatomical pathway that a nerve impulse travels along to produce a reflex is termed the reflex arc. It structurally consists of the receptor, sensory neuron, integration center, motor neuron, and effector.


Why other options are incorrect:

  • Reflex action is the functional behavior or result (e.g., pulling your hand away), whereas the reflex arc is the physical pathway itself.

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.
