Microglia
D
Astrocyte
Verified step by step guidance
1
Understand the role of glial cells in the central nervous system (CNS). Glial cells are non-neuronal cells that provide support, protection, and maintenance for neurons. Different types of glial cells have specialized functions.
Review the function of cerebrospinal fluid (CSF). CSF is a clear fluid that surrounds the brain and spinal cord, providing cushioning, nutrient transport, and waste removal.
Learn about ependymal cells. Ependymal cells are a type of glial cell that line the ventricles of the brain and the central canal of the spinal cord. They are responsible for producing and helping circulate CSF through the movement of their cilia.
Compare ependymal cells to other glial cells listed in the options: Oligodendrocytes form myelin sheaths around axons in the CNS, microglia act as immune cells in the CNS, and astrocytes provide structural and metabolic support to neurons.
Conclude that ependymal cells are the correct answer because they are specifically involved in the production and circulation of cerebrospinal fluid (CSF).
