Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
They are part of glial cells, which share space with neurons in the nervous system.
They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.
For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.
The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.
A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.
Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.
Pressure increase towards earth’s interior because the further deeper you go the higher the rock layers above that apply pressure towards the center of the earth by gravity. In addition , due to this increasing pressure, temperatures also increase because the two parameters are directly proportional.

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions
