The unidirectional flow of a nerve impulse through a multipolar neuron

The unidirectional flow of a nerve impulse through a multipolar neuron across a chemical synapse is due to the fact that

  1. Sodium-potassium pump operates only at the cyton
  2. Myelin sheath prevents its transmission in opposite direction
  3. Neurotransmitters are released by axon endings and not by dendrites
  4. Nissl's granules form proteins which prevent bidirectional flow of nerve impulse
