Myelin, the … WebFollowing nervous system injury, axon regeneration is controlled by neuron-intrinsic and neuron-extrinsic mechanisms ( Table 9.1 ). Neuron-intrinsic signaling pathways that regulate axonal growth and regeneration in the injured vertebrate CNS appear to be evolutionarily conserved. While lower vertebrates spontaneously activate and sustain ... inboxcleaner twitterThe main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber. In unmyelinated fibers, action potentials travel as continuous waves, but, in myelinated fibers, they "hop" or propagate by saltatory conduction. The latter is markedly faster than the former, at least for axons over a certain diameter. Myelin decreases capacitance and increases electrical resistance across the axonal membrane (the axole… inclination\\u0027s jy
