在制作一成年男性左上肢血管神经标本时,发现其拇主要动脉合并掌浅弓、掌深弓多发变异(图1,2)。为积累解剖学资料,现报道如下:该标本尺动脉下行至豌豆骨中点时外径为2.40 mm。下行至豌豆骨中点3.17cm处发出外径为1.64 mm的尺动脉掌深支,该支在距其起点0.38 cm处发出外径为1.34 mm的小指尺掌侧固有动脉。掌深支主干与桡动脉的终末支吻合成掌深弓。在 In the production of an adult male left upper extremity vascular samples, it was found that the main artery of his thumb merged with the palm of the hand bow, multiple changes in the palm of the deep bow (Figure 1, 2). To accumulate anatomical data, are now reported as follows: The specimen ulnar artery down to pea midpoint when the outer diameter of 2.40 mm. Down to the midpoint of the pea bone 3.17cm Department issued a 1.64 mm diameter outer diameter of the dorsal raphe branch, the branch from its starting point 0.38 cm Department issued a 1.34 mm outer diameter of the dorsal raphe tip of the native arteries. Palm deep branch of the main branch of the radial artery and the synthesis of the end of palm kyphosis bow. in
