In marrow-containing nerve fibres, i.e. those surrounded by myelin-forming glial cells, ionscurrents flow from Ranvier-lacing ring to Ranvier-lacing ring with little loss. Only in the area of the Ranvier rings is the cell membrane depolarized and action potential. The AP thus jumps from Ranvierring to Ranvierring, which is why this form of excitation propagation is also called saltatory excitation conduction.
