Verified step by step guidance

Understand the role of myelination: Myelination is the process of forming a myelin sheath around the axons of neurons, which helps increase the speed of electrical impulses along the nerve cells.

Differentiate between the central and peripheral nervous systems: The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes all the nerves outside the CNS.

Identify the cells responsible for myelination in the CNS: Oligodendrocytes are the cells that provide myelination to neurons within the CNS.

Identify the cells responsible for myelination in the PNS: Schwann cells are responsible for myelinating neurons in the peripheral nervous system.

Eliminate incorrect options: Microglia are immune cells in the CNS, and astrocytes provide support and nutrition to neurons in the CNS, but neither are involved in myelination. Therefore, the correct answer is Schwann cells.
