To Contact a Schwann Cell, Where Would a Microprobe Have

Question

To contact a Schwann cell, where would a microprobe have to be inserted in the nervous system?
A) anywhere in the CNS
B) near or at a neuron cell body
C) alongside an unmyelinated axon in the CNS
D) along any axon in the PNS, myelinated or not
E) None of the answers are correct.

Accepted Answer

Schwann cells are found in the peripheral nervous system (PNS) and are responsible for myelinating axons in the PNS, so a microprobe would have to be inserted along any axon in the PNS, myelinated or not, to contact a Schwann cell.
