| Ganglioneuroma is a benign tumor of the sympathetic nervous system that rarely produces symptoms of endocrine dysfunction. |
| The two main ganglionic trunks of the sympathetic nervous system are the cervical and lumbar trunks. |
| 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. |
| The constrictor muscle is supplied by the parasympathetic nervous system, and the dilator by the sympathetic nervous system. |
| They also subdue signals from the sympathetic nervous system and inhibit deleterious overgrowth of damaged heart muscle. |
