Solution
The correct option is A Ependymal cells
Ventricles of the brain are the open cavity of the brain. These are lined by the cells called as ependymal cells. Desmosomes are the special adhesion site which mainly helps for intercellular transport which enables the cells to form a nearly continuous epithelial sheet over the surface of the ventricles and spinal canal. As the junctions between the ependymal cells are loose, CSF is able to diffuse from the ventricles into the central nervous system. The cells surrounding the choroid plexus are connected by tight junctions, which prevent the leakage of substances and fluids from the blood vessels into the CSF. This protects against the unregulated entry of potentially harmful substances into the ventricles and ultimately the central nervous system. So, the correct answer is option A.
