PMDC Verified Question 70 of 86
Neurons are cells adapted for the rapid transmission of electrical impulses. To do this, they have long thin processes called:
A
Axons
B
Myelin sheath
C
Dendrites
D
Schwann cell

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Axons
Concept:

The morphology of a neuron is perfectly adapted for long-distance communication.

Solution:

  • Axons are the elongated, thin processes (fibers) that conduct electrical impulses (action potentials) away from the cell body over long distances (sometimes up to a meter in humans) to target effectors or other neurons.


Why other options are incorrect:

  • Dendrites: Typically short and highly branched; they receive signals rather than transmitting them over long distances.


  • Myelin sheath / Schwann cell: These insulate the axon to speed up transmission, but they are not the "process" 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.
