WebMyelin 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 … WebThe axon carries the action potential to the next neuron. Neurons usually have one or two axons. Some axons are covered with myelin, which acts as an insulator to minimize dissipation of the electrical signal as it travels …
