| S. No. | Myelinated Axon | Non-myelinated Axon |
| 1. | Neurons in which myelin sheath is found are called myelinated or myelinated neurons. | Neurons in which myelin sheath is absent are called unmyelinated axons or non-myelinated neurons. |
| 2. | Their color is white. Therefore they are also called white neuron. | Their color is grey. Therefore they are also called gray neurons. |
| 3. | Schwann cells are found around the neuron which form the myelin sheath. | Schwann cells are found around the neuron but do not form myelin sheath. |
| 4. | Occlusal nerve fibers are found in the spinal and cranial nerves. | Whereas unsheathed nerve fibers are generally found in the autonomic and somatic nervous system. |
| 5. | This increases the speed of nerve transmission compared to uncovered nerves. | The speed of nerve transmission is less as compared to the covered axon. |
