What is the lining epithelium of ventricles of brain?
Ans. is 'a' i.e., Ependyma & 'b' i.e., Ciliated columnar cells Ependymae* Ependyma is the thin epithelial lining of the ventricular system of the brain and the central canal of the spinal cord, made up of ependymal cells.* Ependymal cells are ciliated simple columnar cells.* Ependyma is one of the four types of neuroglia in the central nervous system (CNS).* It is involved in the production of cerebrospinal fluid (CSF), and is shown to serve as a reservoir for neuroregeneration.* The basal membranes of these cells are characterized by tentacle-like extensions that attach to astrocytes.
