Question 3
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level.
The blood-brain barrier is a diffusion barrier which prevents most particles from entering the
central nervous system tissue, keeping the brain and spinal cord separate from general blood
circulation. The blood-brain barrier is formed by the relatively impermeable brain capillaries,
due to the glial cells astrocytes. Maintenance of the blood-brain-barrier is important to
provide a stable chemical environment for the nervous system.
