| 1762395075 | Mirror Neurons | fires both when an animal acts and when an animal observes the same action performed by another | 9 | |
| 1762395076 | Interneuron | within the brain and spine that communicate internally and intervene between motor and sensory neurons | 10 | |
| 1762395077 | Recovery period | Refractory period | 11 | |
| 1762395078 | Neuron stimulation | causes a change in charge (all or none) | 12 | |
| 1762395079 | Depolarization | action potential moves + in - out and so on | 13 | |
| 1762395080 | Action potential | moves down the axon, neural impulse, brief electrical charge that travels down an axon | 14 | |
| 1762395081 | Axon | extension of neuron, ending in branching terminal fibers, messages pass to other neurons/muscles | 15 | |
| 1762395082 | Glial cells | non neural cells that maintain homeostasis: form myelin and provide support and protection for neurons in the brains and PNS | 16 | |
| 1762395083 | reuptake | neurotransmitter's reabsorption by the sending neurons | 17 | |
| 1762395084 | Antagonist molecules | blocks against medicated responses | 18 | |
| 1762395085 | Agonist molecules | causes an action, activate the receptor to produce a biological response | 19 | |
