支配鸡输卵管子宫部交感节后神经元的逆行追踪研究

目的 探讨明支配鸡输卵管子宫部的交感节后神经元的位置。方法 将ＣＢ－ＨＲＰ溶液注入鸡输卵管子宫部浆膜下进行逆行追踪研究。结果 鸡输卵管子宫部受双侧Ｔ１－ＬＳ１３交感干神经节、内脏神经节和肾上腺神经节的交感节后神经元支配，以左侧支配占优势。交感干上的标记细胞成前后两个相对集中区，分别位于Ｌ５－ＬＳ２和ＬＳ８－ＬＳ１２节段，峰值在Ｔ７和ＬＳ１０。结论 虽然鸡输卵管子宫部是左侧发育成熟器官，但其接受双侧交感神经的支配。

STUDY ON SYMPATHETIC POSTGANGLIONIC NEURONAL INNERVATION OF UTERUS OF UTERINE TUBE IN HENS WITH RETROGRADE TRACING METHOD

Objective\ To determine the distribution of the sympathetic postganglionic neurons innervating the uterus of uterine tube in hens. Methods\ CB\|HRP was injected into the wall of the uterus(shell gland)of hens. Results\ The hens uterus was innervated by the bilaterally sympathetic postganglionic neurons from T\-1 to LS\-\{13\} segments of the sympathetic trunk,splanchnic and adrenal ganglia.CB\|HRP labeled neurons in the left side were prominant.In the sympathetic trunk,a good lot of labeled neurons were accummulated in the segments both T\-5\|LS\-2 and LS\-8\|LS\-\{12\}. The greatest concentration of the neurons was in T\-7 and LS\-\{10\}. Conclusion\ The hen's uterus was innervated by the bilaterally sympathetic ganglionic neurons although it was the unilateral organ.
