What is the "blood brain barrier"?
What will be an ideal response?
The endothelial cells comprising the walls of the capillaries that supply blood to the brain are tightly packed together, with minimal pores between them. In addition, parts of glial cells may cover the outside of the capillaries. These comprise a lipid barrier through which non-lipid soluble drugs cannot pass, unless the molecules are compatible with transport proteins that can carry them across these membranes.
