POINT!
| Saltatory conduction is the mode characteristic for the myelinated fibers. The conduction speed is high. |
In myelinated fibers, action potentials are generated only at the Ranvier node. Thus, in saltatory conduction, the speed is fast. The conduction speed of the non-myelinated fibers are slower than that of the myelinated fibers.
