| 摘要: |
| 解剖观察了羊5头、牛3头的胸、腰和荐段交感神经的交通支。结果为,在胸1-12和腰1-3节段,每一脊神经一般均有二条交通支;腰4-8、荐1-4（5）羊(牛)节段,各只有一条交通支;仅在腰1-3(牛)或腰,(羊)节段,有斜交通支;荐段有横交通支。在羊和牛的胸段,前后二交通支在多数节段位于肋间动脉起点的后缘;在腰段通常前支在腰动脉之前,后支在其后。前支细,与脊神经腹支的连接点距椎外侧孔或椎间孔较近;后支较粗,与脊神经腹支的连接点距椎外侧孔或椎间孔较远。胸、腰段交通支的分支类型与马和驴的交通支分型相似。 |

| Abstract: |
| By dissecting 8 calves and sheep (3 calves,5 sheep),the results show that two rami communicantes from each spinal N.in T_(1-13) and L_(1-3);one ramus communicantis exists in either L_(4 6) or S_(1-4(5)) (calf);only obliguus ra- mus is located in L_(1-3) (calf) or L_(2-5)(sheep),and there is a transversus commu- nicantis in sacral section.In general,the two rami communicantes of the T in sheep and calf are behind the Intercostal Arteries.They are before and after Lhe Intercostal Arteries or the deep and shal... |
