在34侧成人标本中,发现左侧臂正中动脉1例。该例臂正中动脉由肱动脉在背阔肌止端下方2cm 平面发出,继而在肱动脉前面下降,至肘窝处过肱二头肌内侧缘、桡侧腕屈肌起端的浅面,沿前臂正中、前臂屈肌群浅面下降,由腕横韧带浅面与掌长肌腱之间入手掌,末端在第一掌骨底平面分为内、外2支。内侧支与掌深弓吻合,外侧支与桡动脉终支吻合替代了掌浅弓(见附图)。该臂正中动脉全长粗细变化不大,起段
In 34 adult specimens, the left arm was found in 1 case of the median artery. The case of the middle of the arm by the brachial artery brachial artery in the dorsalis 2cm plane below the end, then in front of the brachial artery descend to the elbow at the biceps medial margin, radial flexor carpi ulnaris origin, along the forearm In the middle, the forearm flexor group descended superficially, and the palmar longus tendon between the superficial area of the transverse carpal ligament and the palmar long tendon entered into the palm of the hand. The distal end was divided into two parts, inner and outer. The medial branch and the palm of the deep arch anastomosis, lateral branch and radial artery anastomosis to replace the superficial palmar arch (see photo). The arm median artery length changes little, starting segment
