Neuroglia Functions: Astrocytes, Oligodendrocytes, Schwann Cells, Microglia, and Ependymal Cells

What is the role of astrocytes in the brain?

Astrocytes help regulate and supply nutrients and ion concentrations, support the blood-brain barrier (BBB), create trophic factors, and guide synapse formation.

What is the primary function of oligodendrocytes?

Oligodendrocytes myelinate neurons in the central nervous system (CNS).

What is the function of Schwann cells?

Schwann cells myelinate neurons in the peripheral nervous system (PNS) and assist in the repair and regeneration of axons.

What are microglia cells and their function?

Microglia are immune cells that are usually phagocytes who prevent infection and bacteria

What is the role of ependymal cells in the central nervous system?

Ependymal cells create cerebrospinal fluid (CSF), which helps in waste removal and provides cushioning.

what happens to microglia activity as you age

microglia activity increases, increasing the inflamatory responses, harming brain health
