GENERAL HISTOLOGY

Detailed explanation-1: -An ependymal cell is a type of glial cell that forms the ependyma, a thin membrane that lines the ventricles of the brain and the central column of the spinal cord. Their main function is to secrete, circulate, and maintain homeostasis of the cerebrospinal fluid that fills the ventricles of the central nervous system.

Detailed explanation-2: -Ependymal cells line the ventricular spaces of the adult brain. They have a simple ciliated cuboidal morphology. The cilia project into the ventricular space and spinal canal, oscillate approximately 200 times per minute, and are thought to assist the rostrocaudal flow of cerebrospinal fluid.

Detailed explanation-3: -The layer of ependymal-derived cells surrounding the blood vessels of the choroid plexus functions mainly to produce CSF. This is accomplished through the selective uptake of water and certain other molecules from the blood into the cells.
