The difference between Myelinated and Non-Myelinated Nerve Fibre are given below:
Myelinated Nerve Fibre:
1. The nerves that are insulated by a sheath or myelin called myelinated nere fibre.
2. These are made up of lipid & protein and so, appear white.
3. These have nodes of Ranvier which always constant in number.
4. Nerve fibres outside CNS and myelinated.
Non-Myelinated nerve fibre:
1. The nerves which lack such sheath are called non-myelinated nerve fibre.
2. They appear grey because of absence of myelin sheath.
3. They do not have node of Ranvier.
4. Post-ganglionic sympathetic nerves are non-medulated.
