Absolute Refractory Period (1 millisecond) VG Na channels are still inactivated b. Relative Refractory Period (2-3 millisecond) b.i. VG Na channels still open V) Saltatory Conduction a. Big axons wrapped with insulation myelin a.i. Separated by nodes b. AP moves by jumping from node to node faster VI)Generated Potentials (GPs) a. In sensory neurons b. Transduce physical stimulus c.
