Verified step by step guidance

Begin by identifying the main types of glial cells in the central nervous system (CNS) and peripheral nervous system (PNS). Glial cells are non-neuronal cells that provide support and protection for neurons.

Understand the role of astrocytes, which are star-shaped glial cells found in the CNS. They are known for providing structural support, maintaining the blood-brain barrier, and regulating nutrient and ion balance.

Consider the function of oligodendrocytes, which are responsible for forming the myelin sheath around neurons in the CNS, aiding in electrical insulation and signal transmission.

Examine the role of microglia, which act as the immune cells of the CNS, involved in removing debris and pathogens through phagocytosis.

Review the function of Schwann cells, which are similar to oligodendrocytes but are found in the PNS, where they also form myelin sheaths around peripheral nerves.
