Why are action potentials usually conducted in one direction?

#Part-A Aptitude & General Biotechnology
  1. The nodes of Ranvier conduct potentials in one direction.
  2. The brief refractory period prevents reopening of voltage-gated sodium channels.
  3. The axon hillock has a higher membrane potential than the terminals of the axon.
  4. Voltage-gated channels for both Na+ and K+ open in only one direction.
