Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Mechanoreceptors
Concept:

Receptors are classified based on the type of stimulus energy they transduce into electrical signals.

Solution:

  • Pressure is a mechanical force. Mechanoreceptors (like Pacinian corpuscles) are specifically designed to detect mechanical deformation of the receptor membrane caused by pressure or stretch.


Why other options are incorrect:

  • Chemoreceptors: Respond to specific molecules/chemicals.


  • Photoreceptors: Respond to photons (light).


  • Thermoreceptors: Respond to changes in temperature.

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.
