Question

unit 1 - challenge 1.5: the tissue level of or
which of the following glial cells is responsible for the creation of myelin in
the peripheral nervous system (pns)?
a.) oligodendrocyte
b.) schwann cell
c.) astrocyte
d.) satellite cell

Explanation:

• Oligodendrocytes are responsible for myelination in the central nervous system (CNS), not the PNS.
• Schwann cells wrap around axons in the PNS to form myelin sheaths.
• Astrocytes have functions like providing nutrients and maintaining the blood - brain barrier in the CNS, not myelination in the PNS.
• Satellite cells in the PNS mainly provide support and protection to neuron cell bodies, not myelination.

Answer:

B. Schwann cell
