| 1. | The monoamine neurotransmitters norepinephrine, serotonin and histamine are completely unavailable.
|
| 2. | SNRIs are potent inhibitors of the reuptake of serotonin and norepinephrine.
|
| 3. | Stretch receptors cause postganglionic neurons to release norepinephrine ( NE ).
|
| 4. | Under physiologic conditions, however, nitric oxide attenuates norepinephrine vasoconstriction.
|
| 5. | Once in the synapse, norepinephrine binds to and activates receptors.
|
| 6. | It acts primarily as a norepinephrine reuptake inhibitor similarly to desipramine.
|
| 7. | The other hormones measured were norepinephrine, ACTH and cortisol.
|
| 8. | This in turn leads to increased extracellular concentrations of norepinephrine.
|
| 9. | Methylphenidate binds to and blocks dopamine transporters and norepinephrine transporters.
|
| 10. | The neurotransmitter norepinephrine regulates many physiological processes in the body and brain.
