Question

Quizplus · Accepted Answer

Astrocytes do not line the internal cavities of the brain and spinal cord, but rather form the blood-brain barrier, provide structural support, regulate ion concentration, and modulate synaptic transmission among other functions. The cells that line the internal cavities of the brain and spinal cord are ependymal cells.
