Answer» Correct Answer - C There are two types of axons, namely, myelinated and non-myelinated. The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. The gaps between two adjacent myelin sheaths are called nodes of Ranvier. Unmylinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon. |
