掌浅弓变异1例考察报告

在制作标本过程中发现一例掌浅弓异常的标本：经非测量性观察和体质学测量方法考察，发现桡动脉掌浅支和尺动脉终支未吻合成弓。而分别分布于手掌的桡侧和尺侧；桡动脉掌浅支发出2分支即桡侧的拇指桡侧动脉和桡侧的示指桡侧动脉，尺动脉末端发出1条小指尺掌侧动脉和3条指掌侧总动脉，后者于掌指关节处各自又分为2条指掌侧固有动脉，分布于第3～5指的相对缘。初步分析该例标本属掌浅日缺如变异。

In the process of making samples found one case of superficial palmar arch specimens of anomaly： the non measurement obserwttion and physical science measurement methods, found the superficial branch of radial artery palm and ulnar artery branch not fit into a bow, and the distribu tion in the radial side of the hand and foot side respectively; Superficial branch of radial artery zhang sent 2 thumb radial side of the branch is called lateral and radial side shown refers to the radial side of the artery and ulnar artery end send 1 the little finger foot palm side refers to the palm side of total artery and 3, the latter in the digit place each is divided into 2 refers to the volar inherent artery, distributed in 3 ~ 5 refers to the relative mar-- gin. A preliminary analysis of the example mutation samples belong to the superficial palmar arch is absent.
