双峰驼肾动脉分布

应用大体解剖学和血管铸型方法，研究了12峰双峰驼肾动脉的分支分布。结果显示，肾脏的肾动脉在进入肾门之前均分成一背干和一腹干，在肾窦内，背干分为一前支，再由前、后支分别发出背部贤脏的各肾段动脉。腹干不分前、后支，而由主干直接发出腹部肾脏的各肾段动脉。不仅各肾段动脉之间未见吻合，背干及其分支与腹干及其分支之间也无吻合。左肾肾段动脉共13条，右肾肾段动脉12条。表明，双峰驼不仅左、右肾的肾动脉与肾段动脉不尽相同，各肾的背部和腹部的动脉供应也存在差异。肾动脉的背干和腹干是相对独立的。

Distribution of the Renal Artery in the Kidney of Two-Humped Camels,Bactrian Camels

The distribution of the renal artery in 24 kidney s of 12 two-humped camelswas investigated with macroanatomical dissecting and artery casting methods.Beforeentering the hilum renis,the renal artery was divi ded into a dorsal trunk and a ventraltrunk.In the renal sinus,the dorsal trunk was bifurcated into a cranial branch and acaudal branch,from which the segmenta l arteries were origined and radiated into thedorsal part of the kidney.The ven tral trunk,however,went into the renal sinus without thebifurcation,and the seg mental arteries were directly radiated from it into the ventralpart of the kidn ey.No anastomose was seen both between the segmental arteries or thedorsal trun k and the vntral trunk.There were 13 segmental arteries in the leftkindney,but 12 ones in the rigtht.It was showed that,not only the distribution of the leftr enal artery was not the same as that of the right,but also the artery distributi on ofthe dorsal part was different from that of the ventral part in camel kidn ey.
