Neurons in the dorsal root ganglion are located outside the CNS and send their axons to form the dorsal column which are myelinated by
a) astrocytes
b) schwann cells
c) oligodendrocytes
d) ependymal cells
e) microglia
 
yea, it could be either to be honest. I think I saw a Uworld question on this very concept.
 
CC is correct.
Independent of the location of the SOMA, any axon in the CNS( central branch forming the dorsal column in this case) is myelinated by oligodendrocytes and any axon in the PNS( central branch in the dorsal roots and peripheral branch in the dorsal and ventral rami of the spinal nerve in this case) is myelinated by schwann cells.
