In the CNS, axons carry electrical signals from one nerve cell body to another. Meer weergeven 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 … Meer weergeven Myelin is considered a defining characteristic of the jawed vertebrates (gnathostomes), though axons are ensheathed by a type of cell, called glial cells, in invertebrates. These glial wraps are quite different from vertebrate compact myelin, … Meer weergeven The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber.
