<prompt> Saltatory conductions occursConduction in presynaptic to post synaptic neuronMuscles of the T-tubule systemIn. Myelinated axons, the jumping of depolarization from node to nodeA axon can conduct impulse in both direction  <response>: i.e. Myelinated axon, the jumping of depolarization node to node: 87-Ganong 23rd In myelinated axons, depolarization jumps from one node of Ranvier to the next-Saltatory conduction. Orthodromic conduction means conduction in one direction only one neuron called the presynaptic neuron to another neuron called the post synaptic neuron An axon can conduct impulse in one direction only, Orthodromic and opposite direction - Antidromic conduction Synaptic conduction is mostly orthodromic because chemical mediator is localized only in the presynaptic terminal
