Question

Quizplus · Accepted Answer

Ependymal cells of each choroid plexus have tight junctions between them to form a barrier, the blood-cerebrospinal fluid barrier. This barrier controls the flow of substances from the blood into the cerebrospinal fluid, which bathes and protects the brain and spinal cord. Tight junctions are not typically found in microglial cells, astrocyte processes around the pia matter, Schwann cells, or oligodendrocytes around each neuron.
