| Neurons | Nerve cells composed of dendrites and axons. |
| Synapse | The point at which a signal from one neuron is passed to another neuron. |
| Neuroglia | Cells that support the neurons and help communicate with one another. |
| Dendrites | Conduct electircal signals towards the cell body. |
| Axons | Conduct electircal signals away from the cell body. |
| Nerves | Bundles of axoms that carry signals to and from the brain. |
| Central nervous system | Composed of the brain and the spinal cord. This is part of the nervous system that does most of the information processing. |
| Peripheral nervous system | Contains all the neurons involved in receiving information and sending it on to the spinal cord and brain. |
| Cerebrum | Deals with the "higher-level" brain functions. These would include interpreting signals, learning, reasoning, and memory. |
| Gray matter | Composed almost exclusively of the cell bodies of neurons. |
| Corpus callosum | Allows the two hemispheres of the brain to exchange information. |
| Cerebellum | Has many functions mostly oriented around muscle movements. |
| Brain stem | It controls the more basic funtions of the human body, such as breathing, heart rate, and the pressure at which blood is pumped through the body. |
