Which is TRUE regarding nerve conduction

Which is TRUE regarding nerve conduction

  1. All or none phenomenon

  2. Conduction independent of amplitude

  3. Propagated action potential is generated in dendrites

  4. Faster in unmyelinated fibres

Explanation:

Action potential is generated in axon hillock or its initial segment. Then it propagates at a constant velocity and amplitude through the fiber without any decrement. This propagation is faster in myelinated nerve fibers than the unmyelinated fibers.
