Verified step by step guidance

Understand the role of myelin sheaths: Myelin sheaths are insulating layers that surround nerves, including those in the brain and spinal cord, allowing electrical impulses to transmit quickly and efficiently along the nerve cells.

Identify the location: The problem specifies the central nervous system (CNS), which includes the brain and spinal cord.

Differentiate between neuroglial cells: Neuroglial cells in the CNS include astrocytes, oligodendrocytes, and microglia, while Schwann cells are found in the peripheral nervous system (PNS).

Focus on oligodendrocytes: Oligodendrocytes are the type of neuroglial cell responsible for forming myelin sheaths in the CNS. They wrap their extensions around multiple axons to provide insulation.

Contrast with Schwann cells: Schwann cells perform a similar function in the PNS, forming myelin sheaths around individual axons, highlighting the distinction between CNS and PNS myelination.
