Myelin is a lipid-rich material that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, m… WebSchwann cells- glial cells in PNS that have myeline sheath wrap around only one axon location of satellite cells suround neuron cell bodies fuction of satellite of cells support and nutrition to the neuron cell body and protect neuron from heavy metal poisons such as lead and murcury How satellite cells protect neuron from heavy metal poisons
