Question

The myelin sheath in the peripheral nervous system is formed by which cells?

RankGuru · Accepted Answer

1. **Neural Support**: Neurons are supported by various non-conducting glial cells.
2. **Myelination**: The myelin sheath acts as an electrical insulator for axons.
3. **In the PNS**: **Schwann cells** wrap around individual nerve fibers in the Peripheral Nervous System to form the myelin sheath.
4. **In the CNS**: **Oligodendrocytes** perform this function in the Central Nervous System (brain and spinal cord).
5. **Others**: Astrocytes provide metabolic and structural support; Microglia are the resident immune cells of the CNS.
