Question

Quizplus · Accepted Answer

Astrocytes do not line the internal cavities of the brain and spinal cord, instead they are found in the parenchyma of the CNS where they perform various functions including holding neurons together, inducing the formation of the blood-brain barrier, and taking up excess ions to help maintain proper brain ECF ion concentration.
