axons are long, slender projections of a nerve cell (neuron) that function to transmit electrical impulses, known as action potentials, away from the cell body to other neurons, muscles, or glands, essentially carrying messages to different parts of the body.Oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS) produce the myelin sheath. Unmyelinated Is slower.
