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, … j basket boba instructionsWebIn peripheral nerves, Schwann cells form the myelin sheath, which allows the efficient propagation of action potentials along axons.
