Solution

Myelinated fibres:
Myelinated fibres are the nerve fibres that are covered by a myelin sheath and act as an insulating, protective sheath located between neurilemma and axon.
Non-myelinated fibres:
The nerve fibres without myelin sheath are called non-myelinated fibres.
Myelinated fibres Non-myelinated fibres
Myelinated fibres are the nerve fibres that are covered by a myelin sheath
The nerve fibres without myelin sheath are called non-myelinated fibres
2. These consist of nodes of Ranvier. 2. These do not consist of nodes of Ranvier.
3. Myelin sheath prevents the loss of the impulse during conduction. 3. These can lose the nerve impulse during conduction.
