There is a gap in the parasympathetic nervous system sushumna but no gap in the sympathetic nervous system at the navel 这种方法只会消耗掉储存在能量中心的能量。副交感神经在脐部有所中断，而交感神经却没有。
The gross manifestation of this subtle energy , in the sushumna channel of the spinal cord , is termed the parasympathetic nervous system 这个位于脊柱中脉的微妙能量在粗浅层面物质界表现为副交感神经系统。各个能量中心
But when a human child is born and the umbilical cord breaks , a gap is created in the sushumna the subtle channel in the spinal cord 当婴孩出世，切断了脐带的时候，他的中脉便出现了一道洪沟。从外面看，我们能看见副交感神经系统太阳神
The parasympathetic relaxes the plexuses while the sympathetic squeezes the energy by constricting them . one fills in the vitality and the other consumes it 副交感神经系统令神经丛得以舒缓，而交感神经系统则是去挤压它，使之释放出更多的能量。
For example , if we want to increase the rate of our heartbeat , we can do so by exerting ourselves activity of the sympathetic nervous system 例如，如果我们要增加心跳的速度，我们可以通过交感神经系统的活动对心脏施加压力。可是副交感神经系统却会使心跳回复正常。
For example , sympathetic can restrain bowel to move and secrete a function of the path , and move and secrete a function what the parasympathetic nerve can enhance bowel to however 例如，交感神经能抑制肠道的运动和分泌功能，而副交感神经却可以增强肠道的运动和分泌功能。
The skin blood circulation , the gland secretion and so on theimportant physiological activity , ( and parasympathetic nerve iscomposed of the plant nerve by sympathetic nerve ) regulates 皮肤的血液循环、腺体的分泌等重要生理活动，均由植物神经（由交感神经和副交感神经组成）调控。
Affect athletic result : human body eats the parasympathetic nerve inside rear body easy be restrained , if this opportunity body wants to take exercise , athletic effect can sell at a discount . 4 3 .影响运动效果：人体进食后体内副交感神经易受到抑制，此时机体若要锻炼，运动效果会打折扣。
Most investigators rectify this information by suggesting that it represents an initial exaggerated sympathetic output followed by parasympathetic activation and then sympathetic withdrawal ( 2 ) 越来越多的研究者认为，最初人们过大的估计了交感神经的作用，而事实应该是副交感神经系统被激活，交感神经功能减退[ 2 ] 。
Other less frequent occurrences with administration of alpha 2 agonists include bradycardia and sinoauricular block , which hae been suggested to occur more commonly in young patients due to their high leel of parasympathetic tone ( 5 ) 给与- 2受体激动剂后较少出现的作用包括心动过缓和窦房性传导阻滞，这些作用更常发生在年轻人，因为其副交感神经张力处于高水平[ 5 ] 。
