<prompt> Which is TRUE regarding nerve conductionAll or none phenomenonConduction independent of amplitudePropagated action potential is generated in dendritesFaster in unmyelinated fibres  <response>: An action potential is generated in axon hillock or its initial segment. Then it propagates at a constant velocity and amplitude through the fibre without any decrement. This propagation is faster in myelinated nerve fibres than the unmyelinated fibres.
