WebbThe myelin sheath is a layer of fatty tissue that covers and insulates the axon of a neuron. Its primary function is to speed up the transmission of electrical signals (action … WebbThe nodes of Ranvier, illustrated in Figure 3 are gaps in the myelin sheath along the axon. These unmyelinated spaces are about one micrometer long and contain voltage gated Na + and K + channels. Flow of ions through these channels, particularly the Na + channels, regenerates the action potential over and over again along the axon. This ‘jumping’ of the …
