PATHOLOGY

Detailed explanation-1: -Astrocytes are support cells of the CNS. These are by far the most numerous type of glial cell, and therefore the most numerous type of cell in the nervous system.

Detailed explanation-2: -ependymal cell, type of neuronal support cell (neuroglia) that forms the epithelial lining of the ventricles (cavities) in the brain and the central canal of the spinal cord.

Detailed explanation-3: -Ependymal cells line fluid-filled ventricles of the brain and the central canal of the spinal cord. They are involved in the production of cerebrospinal fluid, which serves as a cushion for the brain, moves the fluid between the spinal cord and the brain, and is a component for the choroid plexus.
