The walls of capillaries throughout the body and within the CNS are formed by endothelial cells, however, within the CNS the capillary endothelial cells are very tightly packed. This density of cells restricts the passage of substances out of the bloodstream much more than endothelial cells in capillaries elsewhere in the body. This is the basis of the [[Blood Brain Barrier - Anatomy & Physiology|blood brain barrier]].

==Neuronal Transport Mechanisms==
Neurons are often quite large when compared to other cell types within the body and therefore the transport of molecules, organelles and other elements important to the cell becomes more difficult and equally more important. Neurons have developed a number of mechanisms to transport material throughout the cell.
