Question

multiple choice question
which type of glial cell produces the myelin sheath in the pns?
satellite cell
schwann cell
oligodendrocyte
ependymal cell

Explanation:

In the peripheral nervous system (PNS), Schwann cells are responsible for producing the myelin sheath that insulates axons. Satellite cells are associated with neuron - cell body support in PNS ganglia. Oligodendrocytes produce myelin in the central nervous system (CNS), not PNS. Ependymal cells line the ventricles of the brain and central canal of the spinal cord and are involved in cerebrospinal fluid production and circulation.

Answer:

B. Schwann cell
