Which CNS cell lines brain ventricles and spinal canal?

Explanation:
Ependymal cells line the brain ventricles and the spinal cord’s central canal. They form the epithelial interface of the ventricular system and help produce and circulate cerebrospinal fluid, often with motile cilia to move CSF through the cavities. Astrocytes mainly provide support and contribute to the blood-brain barrier; oligodendrocytes create myelin around CNS axons; microglia act as resident immune cells. Because only ependymal cells specifically line those CSF-filled cavities, they are the cells described.
