Detailed explanation-1: -Ependymal cells are ciliated-epithelial glial cells that develop from radial glia along the surface of the ventricles of the brain and the spinal canal. They play a critical role in cerebrospinal fluid (CSF) homeostasis, brain metabolism, and the clearance of waste from the brain.
Detailed explanation-2: -Ependymal Cilia Propelling the Circulation of Cerebrospinal Fluid. The directional flow of CSF depends directly on ependymal cilia within the ventricular system (Lee, 2013; Kumar et al., 2021). Ependymal cilia can be found on ECs all across the brain, projecting up to 20 microns from the cell (Zhang J. et al., 2020).
Detailed explanation-3: -Ependymal cells form an epithelial layer lining the cerebral ventricles. Functioning as a barrier between the brain parenchyma and cerebrospinal fluid (CSF), they play a role in cerebral fluid balance, toxin metabolism, and secretion [1].
