Explanation:

Identify glial cells and their locations

Using the Nervous System Anatomy knowledge point, we distinguish between Central Nervous System (CNS) and Peripheral Nervous System (PNS) glial cells. Oligodendrocytes, ependymal cells, microglia, and astrocytes reside in the CNS, while Schwann cells reside in the PNS.

Match oligodendrocyte function

Oligodendrocytes form myelin sheaths around axons in the CNS.

• Matching item: "Make myelin in CNS" (abbreviated as "Make myelin..." in the stack).

Match Schwann cell function

Schwann cells form myelin sheaths around axons in the PNS.

• Matching item: "Make myelin in PNS" (abbreviated as "Make myelin..." in the stack).

Match ependymal cell function

Ependymal cells line the ventricles of the brain and the central canal of the spinal cord, where they produce and circulate cerebrospinal fluid.

• Matching item: "Make CSF".

Match microglia function

Microglia act as specialized macrophages in the CNS, clearing cellular debris and pathogens via phagocytosis.

• Matching item: "Phagocytosis" (abbreviated as "Phag..." in the stack).

Match astrocyte function

Astrocytes support neurons and help form the protective blood-brain barrier (BBB) regulating the chemical environment.

• Matching item: "Blood-brain barrier" (abbreviated as "Blood..." in the stack).

Answer:

Glial Cell	Function
Schwann cell	Make myelin in PNS
Ependymal cells	Make CSF
Microglia	Phagocytosis
Astrocytes	Blood-brain barrier
