The upcoming discussion will update you about the differences between Medullated and Non-Medullated Nerve Fibres.
Difference # Medullated Nerve Fibres:
1. Medullary sheath is present.
2. They appear white in fresh state.
3. Nodes of Ranvier are present at intervals.
4. Collateral nerve fibres are present.
5. They are generally present in the white matter of brain and spinal cord and in cranial and spinal nerves.
6. They carry impulses faster than non- medullated nerve fibres.
Difference # Non-Medullated Nerve Fibres:
1. Medullary sheath is absent.
2. They appear grey in fresh state.
3. Nodes of Ranvier are absent.
4. Collateral nerve fibres are absent.
5. They are present in autonomic nerves.
6. They carry impulses slower than medullated nerve fibres.
