| Too much sympathetic nervous system activity can be associated with stress, anxiety, and dysphoric mood. |
| Drugs can modulate the activity of the sympathetic nervous system by affecting the synthesis, storage, release or reuptake of noradrenaline. |
| The autonomic nervous system is divided into two more systems: the sympathetic nervous system and the parasympathetic nervous system. |
| If the sympathetic nervous system is damaged, however, the blood vessels do not constrict and blood pressure progressively decreases. |
| Here we will activate your sympathetic nervous system using a famous model pain stimulus: dunking your hand in ice water. |
| The sympathetic nervous system, not white blood cells, is critically important in the regulation of energy expenditure and thermogenesis. |
