| The sympathetic nervous system pumps the body up, but when you take a deep breath the parasympathetic nervous system kicks in and starts to wind the system down. |
| This 10-second delay is more in keeping with the behavior of the sympathetic than the parasympathetic nervous system. |
| The parasympathetic nervous system primarily modulates visceral organs such as glands. |
| Asanas stimulate the parasympathetic nervous system, whilst exercises stimulate the sympathetic nervous system. |
| It also inhibits the action of acetylcholine at the postganglionic nerve endings of the parasympathetic nervous system. |
| The constrictor muscle is supplied by the parasympathetic nervous system, and the dilator by the sympathetic nervous system. |
