Some astrocytes have cilia that help keep the fluid in the nervous system moving.

Question

Quizplus · Accepted Answer

Astrocytes are a type of glial cell in the brain and spinal cord that perform many functions, including biochemical support of endothelial cells that form the blood-brain barrier, provision of nutrients to nervous tissue, maintenance of extracellular ion balance, and repair of the brain and spinal cord following traumatic injuries. However, they do not have cilia that move fluid in the nervous system; the movement of cerebrospinal fluid is primarily driven by the ciliated ependymal cells lining the ventricles of the brain.
