Question
Differentiate between :
Myelinated and Non-myelinated Axons

Answer

Differences between Myelinated Axon and Non-myelinated Axon
S. No.Myelinated AxonNon-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.
