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