Question

Quizplus · Accepted Answer

Astrocytes are responsible for the exchange of nutrients and other substances between CNS neurons and blood vessels. They form the blood-brain barrier which regulates the movement of molecules in and out of the brain. Microglia, oligodendrocytes, satellite cells, and Schwann cells do not have this function.
