| 10810145410 | Dendrite | the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body |  | 0 |
| 10810152001 | Axon | the neuron extension that passes messages through its branches to other neurons or to muscles or glands |  | 1 |
| 10810162438 | Sending Neuron | presynaptic neuron | | 2 |
| 10810166035 | synaptic gap | space between the axon terminal of one neuron and the receptors of the next neuron |  | 3 |
| 10810170169 | Nucleus | Control center of the cell |  | 4 |
| 10810176928 | Terminal Branches | The branched end of the axon that contains neurotransmitters. |  | 5 |
| 10810184103 | Vesicle | A membrane bound sac that contains materials involved in transport of the cell. |  | 6 |
| 10810198748 | Cell Body (soma) | contains the nucleus and other parts of the cell needed to sustain its life |  | 7 |
| 10810201551 | Myelin Sheath | covers the axon of some neurons and helps speed neural impulses |  | 8 |
| 10810204326 | Action Potential | All or none; Either there is enough stimulus from the neurotransmitter to activate the action potential or there is not. Either it fires and depolarizes sending the message or it doesn't. | 9 | |
| 10810215380 | Neurotransmitters | chemical messengers that cross the synaptic gaps between neurons |  | 10 |
| 10810218969 | Types of Neurotransmitters | Acetylcholine (Ach), Serotonin, Norepinephrine, Dopamine, Endorphins, GABA, and Glutamate. | 11 | |
| 10810224756 | Agonist | mimics a neurotransmitter, fitting into the receptor site and exiting the site. (morphine mimics endorphins, stimulating mood and pain sensation) | 12 | |
| 10810228959 | Antagonist | Fits into the receptor site but is not similar enough to stimulate it. instead it BLOCKS or nhibits the function of the neurotransmitter receptor (stops ezcess or is why we don't have enough). | 13 | |
| 10810235160 | Receptor Sites | Part of the dendrite that receives the neurotransmitter |  | 14 |
| 10810275078 | Acetylcholine (ACH) | -Excitatory -muscle function - learning and memory - attention - Too much:Muscle Spasms -Too little: Alzheimer's | 15 | |
| 10810282698 | Dopamine | -Inhibitory -Mood and emotion - Arousal - Too much: Schizophrenia and drug addiction -too little: Parkinson's disease. | 16 | |
| 10810335882 | Seratonin | -Inhibitory - mood regulation -hunger and sleep - too much: hallucinations -too little: depression and mood disorders | 17 | |
| 10810353409 | norepinephrine | -excitatory -arousal and alertness especially in fight or flight response. - mood elevation -too much: anxiety -too little: mental disorders, specifically depression | 18 | |
| 10810374896 | GABA | - inhibitory - Brain's main inhibitory neurotransmitter - regulates sleep-wake cycles - Too much: sleep and eating disorders - too little: anxiety, epilepsy, insomnia, Huntington's disease | 19 | |
| 10810399921 | Glutamate | - Exitatory - Brain's main excitatory neurotransmitter -basis of leaning and long term memory - too much: overstimulation of brain which can cause migraines and siezures - too little: N/A | 20 | |
| 10810431662 | Endorphins | - Inhibitory -pain control - stress reduction - positive emotions -too much: artificial highs, inadequate response to pain - too little: potential involvement in addiction, especially opiates | 21 |
