| Cells that make up the brain | Neurons |
| Approximate number of neurons in the brain | 100 Billion |
| When neurons are lost, they- | -grow back |
| Makeup of the neuron | Dendrites , cell body, axon, Myelin Sheath, axon terminals |
| Neuron receivers | Dendrites |
| Contains nucleus of neuron | Cell body |
| Neuron conducting fiber | Axon |
| Insulating fatty layer that speeds neuron transmission | Myelin Sheath |
| Neuron transmitters | Axon Terminals |
| When there are too many transmitters, a transmitter is sent back in the process of- | -Reuptake |
| Electricity that goes through the neurons | Action Potential |
| Elements used in action potential | Sodium and Potassium |
| The minimum amount of information the dendrite needs to recieve | Threshold |
| Too much dopamine causes- | -Schizophrenia |
| Too little dopamine causes- | -Parkinsons |
| Triggers hunger and mood | Serotonin |
| Too little serotonin causes- | -Depression |
| Triggers memory and learning | Acetylcholine (Ach) |
| Too little Acetylcholine causes- | Alzheimer's |
| Body's natural pain reliever, causes addiction | Endorphins |
