WebThese layers form the myelin sheath. Much like the insulation around an electrical wire, the myelin sheath enables nerve signals (electrical impulses) to be conducted along the nerve fiber with speed and accuracy. When the myelin sheath is damaged, nerves do not conduct electrical impulses normally. Sometimes the nerve fibers are also damaged. WebMyelin it contains Evolutionarily, the benefit of a single axon projection vs. multiple neurons in between are: (3) - faster conduction bc there's less synaptic delay - more efficient > only need to supply 1 neuron instead of multiple - no interruptions due to cell division Which portion of a nerve takes up the most volume?
