| 摘要: |
| 本文对北京鸭(Anas domestica L.)的交感神经系统进行大体解剖。北京鸭交感神经系统的主要特点如下:在北京鸭的颈部交感干第,颈椎及第2颈椎部均有交感神经节。颈动脉背侧神经上未见有神经节。胸部交感干的前段有付节间支,而后段缺如。交感神经节与脊神经节在颈段是分离的;在胸段密接;在腰荐段又是分离的,并有一定长度的交通支。系膜前神经节一对,其前方有交通支接内脏大神经的内脏神经节;其后接一长神经节应名主动脉肾神经节。腹腔神经丛没有直接与返神经的交通支,而多数例在腺胃腹侧有一支与迷走神经相交通。肠神经的回肠段常见有神经节;空肠段可分为二部分,后段与血管平行,前段则与血管交叉。在肠神经与迷走神经间没有直接的交通支。 |

| Abstract: |
| This paper deals with gross anatomy of the sympathetic nervous system of the Beijing white Duck (Anas domesticus L.) 15 young and adult ducks were used,and each was observed on both sides, the total were 30.The main characteres are as follows. There are also the sympatnetic ganglia at the parts of atlas and he epistropheus in the neck of the Beijing white duck.On the retro- carotid nerves no ganglia ean be seen.There are accessory intergangli- onic rami at the cranial part of the thoracic sympathetic trunk;... |
