____________ Form the Myelin Sheath Around Axons in PNS

Question

____________ form the myelin sheath around axons in PNS.
A)Oligodendrocytes
B)Microglial cells
C)Ependymal cells
D)Astrocytes
E)Schwann cells

Accepted Answer

Schwann cells are responsible for forming the myelin sheath around axons in the peripheral nervous system. Oligodendrocytes form the myelin sheath in the central nervous system, while microglial cells are immune cells that remove damaged or dead cells. Ependymal cells line the ventricles of the brain and help produce cerebrospinal fluid. Astrocytes have many functions, including maintaining the blood-brain barrier and regulating neurotransmitter levels.
