| axon | the part of a nerve cell that conducts impulses away from a cell body |
| blood brain barrier | a barrier formed by special characteritics of capillaries to prevent certain chemicals from moving to the brain |
| cell body | the main part of a neuron from which axons and dendrites extend |
| central nervous system | brain and spinal cord |
