双峰驼胫前动脉和足背动脉解剖

Dissection of Cranial Tibial Artery and Dorsal Ped Artery in Bactrian Camel

采用血管内灌注颜料的方法解剖观察了双峰驼胫前动脉和足背动脉的分支及分布情况。发现胫前动脉是动脉的主干延续，其主要侧支有胫前返动脉、小腿骨间动脉、外侧踝前动脉和内侧踝前动脉。足背动脉的侧支有跗外侧动脉、跗内侧动脉、跗穿动脉和趾伸肌腱动脉，其中趾伸肌腱动脉在其它家畜未见报道。

The distribution and the branches of the cranial tibial and dorsal ped arteries in seven hind limbs of bactrian camels were dissected and studied by means of the introvascular infused oilcolor. The results are as follows: the cranial tibial artery is continuation of the popliteal artery and it gives off the recurrent cranial tibial artery, the interosseous artery of the leg, the lateral cranial malleolar artery, and the medial cranial malleolar artery. The dorsal pedal artery gives off the medial tarsal, lateral tarsal, perforating tarsal arteries, and the artery of tendon of digital extensor. The artery of tendon of digital extensor is collateral branch of dorsal metatarsal artery Ⅲ, and it have been not reported in other domestic animals.
