Unmyelinated nerve fiber is:
 
1. Not enclosed by a Schwann cell and hence not enclosed by a myelin sheath.
2. Enclosed by a Schwann cell that does not form a myelin sheath.
3. Not enclosed by a Schwann cell but enclosed by a myelin sheath formed by oligodendrocytes.
4. Not found in the autonomous and the somatic neural system.
