What type of nerve is not covered by a protective myelin sheath?

Nonmyelinating Schwann Cells

Some afferent and autonomic nerve fibers lack myelin sheath. These are the unmyelinated fibers and are smaller, since typically the diameter of an axon has to be larger than 1 μm for myelination to commence. After birth in the rodent, SCs diverge in myelinating and nonmyelinating cells.
