difference between myelinated and unmyelinated axon

 Difference between myelinated and unmyelinated sheath

Myelinated sheath

Myelinated nerve fibers contains a myelin sheath.

White in colour

Consist of nodes of ranvier

Speed of transmission of nerve impulses is high.

Include most peripheral nerve

Long axon nerve fibers are myelinated

Myelin sheath prevents loss of the impulse during conduction.

Myelin nerve fibre; spinal nerve, cranial nerve

Unmyelinated sheath

Unmyelinated nerve fibers Donot contain myelin sheath.

Grey in colour

Donot consist of nodes of ranvier

Speed of transmissions of nerve impulse is slow.

Include small axon neuron in CNS.

Short axon nerve fibers are unmyelinated.

Can loss of nerve impulse during conduction.

Non-myelinated nerve fibers; autonomic nervous system, somatic nervous system
