Action potential transmission in the PNS is decreased if which cells are damaged?
A)astrocytes
B)microglia
C)oligodendrocytes
D)Schwann cells

Question

Quizplus · Accepted Answer

Schwann cells are responsible for the production and maintenance of the myelin sheath around axons in the peripheral nervous system (PNS). Myelin sheath facilitates the transmission of action potentials along the axons. Damage to Schwann cells leads to demyelination, which slows down or prevents the transmission of action potentials, resulting in decreased function of the PNS. Astrocytes, microglia, and oligodendrocytes are glial cells found in the central nervous system and do not play a direct role in the myelination of PNS axons.
