| 5235339931 | Biological psychologists | Study links between biological activity and psychological events. | 0 | |
| 5235343776 | Dendrite | Receive messages from other neurons. |  | 1 |
| 5235347013 | Cell Body | Is in charge of the neuron's activities. |  | 2 |
| 5235350415 | Nucleus | contains the genetic material of the cell. |  | 3 |
| 5235353040 | Axon | sends messages from the cell body to the dendrites of other neurons. |  | 4 |
| 5235388960 | Axon Terminals | Are the hair like ends that receive the message. |  | 5 |
| 5236628837 | Myelin Sheath | covers the axons insulates them and speeds their impulse. |  | 6 |
| 5236692631 | Action potential | forms an electrical charge that goes down its axon. |  | 7 |
| 5236704754 | Refractory period | The resting period after the neuron fires. | 8 | |
| 5236711535 | Threshold | The level of stimulation required to trigger a neural impulse. (To be activated) | 9 | |
| 5236720101 | All-or-none response | the neuron's reaction to firing or not firing. |  | 10 |
| 5236735390 | Synapse | The gap between the axon tip of sending neuron and the dendrite/cell body meet. |  | 11 |
| 5236743035 | Neurotransmitters (A key to a lock) | When the action potential reaches the knob-like terminals at an axon's end, where it reaches chemical messages into the gap. |  | 12 |
| 5260198948 | Reuptake | the sending neuron reabsorbs the excess neurotransmitters. | 13 | |
| 5261246573 | Acetylcholine (ACh) | - Plays a role in learning and memory - Contracts after being released into muscle cells - Enables muscle action - Lack of it can cause Alzheimer's Disease (ACh neurons deteriorate) - If blocked, we end up paralyzed | 14 | |
| 5261276690 | Dopamine | - Influences movement, learning, attention, and emotion - Activates reward pathway - Oversupply = Schizophrenia - Undersupply = tremors and decreased mobility in Parkinson's disease - Drugs like heroin increases release of neurotransmitter - May be treated with L-DOPA | 15 | |
| 5261313202 | Serotonin | - Affects mood, hunger, sleep, and arousal - Undersupply = Depression - Some antidepressant drugs raise serotonin levels (aggressive behavior) - Zoloft and Paxil | 16 | |
| 5261364440 | Norepinephrine | - Controls alertness and arousal - Undersupply = depress mood - Signals body to dangers | 17 | |
| 5261388385 | Gaba (Gamma-Aminobutryic Acid) | - A major inhibitory nuerotransmitter - Undersupply = seizures, tremors, and insomnia - Huntington's disease | 18 | |
| 5261407529 | Glutamate | - A major excitatory neurotransmitter involved in memory - Oversupply = Migraines and seizures | 19 | |
| 5261424249 | Endorphin | - In response to pain or rigorous exercise - "Runner's high" - | 20 | |
| 5262189628 | Agonist | Mimic neurotransmitters | 21 | |
| 5262193062 | Antagonist | Block neurotransmitters | 22 |
