, 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.
