I: | Myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. |
II: | Unmyelinated nerve fibre is not enclosed by a Schwann cell or a myelin sheath. |
III: | Myelinated nerve fibres are found in spinal and cranial nerves. |
IV: | Unmyelinated nerve fibres are commonly found in autonomous and somatic neural systems. |
