Which glial cells could be found in the choroid plexus?

• A. Astrocytes
• B. Microglial cells
• C. Ependymal cells
• D. Schwann cells

Answer: (C)

Ependymal cells line the ventricles of the brain, and the choroid plexus is a specialized region of this ventricular lining. These cells form the epithelial layer of the choroid plexus and are responsible for producing cerebrospinal fluid, aided by their microvilli and transport systems. They also help establish the blood–CSF barrier through tight junctions between the lining cells. The other glial types have different roles or locations: astrocytes support neural tissue and contribute to the blood-brain barrier in other contexts; microglia are the CNS immune cells; Schwann cells myelinate peripheral nerves. So, the cells you’d find in the choroid plexus are ependymal cells.
