| 10953239582 | refractory period | the time after a neuron fires or a muscle fiber contracts during which a stimulus will not evoke a response |  | 7 |
| 10953239583 | threshold | the level of stimulation required to trigger a neural impulse |  | 8 |
| 10953239584 | synaptic gap/synapse | space between the axon terminal of one neuron and the dendrite receptors of the next neuron |  | 9 |
| 10953239585 | all-or-none principal | law that neuron either generates an action..or nothing happens at all. Nothing in-between. | 10 | |
| 10953239586 | neurotransmitter | chemical used by a neuron to transmit an impluse across a synapse to another cell |  | 11 |
| 10953239587 | excitatory effect | a neurotransmitter effect that makes it more likely that the receiving neuron will generate an action potential, or "fire" | 12 | |
| 10953239588 | inhibitory effect | a neurotransmitter effect that makes it less likely that a receiving neuron will generate an action potential or "fire" | 13 | |
| 10953239589 | antagonist | a chemical which blocks the activity of neurotransmitter |  | 14 |
| 10953239590 | agonist | a chemical that mimics the action of a neurotransmitter |  | 15 |

| 10953239601 | autonomic nervous system | the part of the peripheral nervous system that controls the glands and the muscles of the internal organs |  | 26 |
| 10953239602 | sympathetic division (sympathetic N.S) | the part of the autonomic nervous system that arouses the body to deal with perceived threats |  | 27 |
| 10953239603 | parasympathetic division (Parasympathetic N.S.) | the part of the autonomic nervous system that maintains normal body functions; it calms the body ever conserves energy |  | 28 |
| 10953239604 | endocrine system | glands that secrete hormones |  | 29 |
