Myelin is a sheath of lipid surrounding an axon of the nerve fiber. 4 A increase leakage of ions across the membrane B increase a membranes ion permeability C decrease axonal conduction velocity D decrease ion permeability in the nodes of Ranvier E reduce a membranes ion permeability. Neurons Biology For Majors Ii Asked Nov 16 2019 in Psychology by Mybaby313 general-psychology. . The main function of the axon is to carry electrical impulse from one neuron to the another neuron. However it took a long while to recognize the mechanistic complexity both of myelination by oligodendrocytes and Schwann cells and of their cellular interactions. Since myelin sheath provides insulation to axons this allows these axons to conduct electrical signals at a higher speed than if they were not insulated by myelin. Greater the diameter faster speed of conductance. It is the vehicle for carrying neurotransmitters. Each Schwann cell myelinat...
