Ciliated ependymal cells: A) help form the blood-brain barrier. B) circulate cerebrospinal fluid. C) form myelin in the brain an
masha68 [24]

Ciliated ependymal cells:<u> circulate cerebrospinal fluid.</u>

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.
