BCT Lab Practical 1 Practice Test

Schwann cells make ______ in the CNS.

None of the above Myelin CSF Mucus

Correct Answer:

None of the above

Explanation:

In the central nervous system, myelination is done by oligodendrocytes, not Schwann cells. Schwann cells are the glial cells that form the myelin sheath around peripheral nerves. CSF is produced by the choroid plexus ependymal cells, and mucus is produced by mucous membranes, not by Schwann cells. Therefore, Schwann cells do not make any of the listed substances in the CNS, so none of the options apply.
