北京鸭输卵管血管分布的形态学研究

The Anatomical Study on the Distribution of Vessels in the Oviduct of Beijing Ducks

采用大体解剖学方法,观察了20羽北京鸭输卵管血管分布。结果表明:北京鸭输卵管动脉有输卵管前、中、后动脉和阴道动脉;输卵管静脉通常与同名动脉伴行,但缺输卵管后静脉,这些血管均位于鸭体左侧。输卵管前动脉一般有1条,起始于左髂外动脉的耻动脉,分布于输卵管漏斗部和膨大部;输卵管中动脉起于左肾后动脉,主要分布于输卵管峡部和子宫前部;输卵管后动脉起始于左髂内动脉或左阴部外动脉,主要供应子宫后部的血液;阴道动脉起于左阴部内动脉,分布于阴道部。

The distribution of vessels in the oviducts were studied in 20 Beijing ducks. The results are as follows： The arteries suppling oviduct of the Beijing ducks contained oviductalis cranialis, media, caudalis and vaginalis. The veins drainaging oviduct were stretched along the above ateries and the vessels were situated on the left side of the body, but there was no caudal oviductal vein. The anterior oviductal artery arose from the pubic artery of the left external iliac artery and distributed to the infundibulum and the magnum of the oviduct. The middle oviductal artery arose from the left caudal renal artery and distributed to the isthmus and shell gland of the oviduct. The caudal oviductal artery arose from the left external pudendal artery or left internal iliac artery and distributed to the caudal part of uterus and the cranial part of vagina. The vaginal artery arose from the left internal pudendal artery of median sacral artery and distributed to the caudal part of vagina.
