Question 7

4 / 4 pts

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.
