Answer

Saltatory propogation

Continuous propogation
  • Saltatory propogation of action potential occurs in myelinated axons.
  • Continuous propogation of action potential occurs in non-myelinated axons.
  • In saltatory propogation, the action potential jumps from one node of Ranvier to another.
  • In continuous propogation, the action potential travels through whole length of the axon.
  • Saltatory conduction is most effective as :
    - It is swift
    - Less energy is used
    - Less use of sodium-potassium pumps
  • Continuous propogation is comparatively not effective as :
    - It is slow
    - More energy is needed.
    - More sodium-potassium pumps are used.
