  • Myelinated nerve fibers are nerve fibers that are insulated by a myelin sheath whereas unmyelinated nerve fibers are nerve fibers that do not have a myelin sheath.
  • Myelinated neurons are neurons whose axons are surrounded by myelin; the myelin has has an insulating effect and allows the axons to conduct neural impulses faster.
  • Myelinated nerve fibres are found in spinal and cranial nerves where signals have to be conducted at a faster rate.
  • Unmyelinated nerve fibres are commonly found in autonomic and somatic nervous systems.
