Questions and Answers

Which cells are responsible for forming myelinated coverings around axons in the peripheral nervous system?

  • Oligodendrocytes
  • Astrocytes
  • Microglia
  • Schwann cells (correct)

    • What is one key difference between myelination in the peripheral nervous system (PNS) and the central nervous system (CNS)?

  • The PNS has a higher number of internodes compared to the CNS
  • The PNS has unmyelinated coverings, while the CNS does not
  • The PNS has multiple Schwann cells covering a single axon, while the CNS does not (correct)
  • The PNS has faster myelin regeneration compared to the CNS

    • Which division of the nervous system has a higher regenerative capacity for damaged myelin?

  • Neither the PNS nor the CNS have regenerative capacity
  • Both the PNS and CNS have equal regenerative capacity
  • Peripheral nervous system (PNS) (correct)
  • Central nervous system (CNS)
