【摘要】 解剖成人上肢标本34例,观察、测量肱骨滋养动脉39支。结果表明,肱骨滋养动脉多起于肱动脉,占79.41%;起于肱深动脉者占8.82%;其它起于尺侧上副动脉和桡侧副动脉。肱骨滋养动脉起始端外口径1.16毫米,入滋养孔处外口径0.67毫米。滋养动脉主干平均长度为22.5毫米。另外发现,滋养动脉长度和入骨位置均与其起源有关。更多还原

【Abstract】 34 cases of the upper limbs were dissected,and 39 cases of nutrient arteries in humerus were obsered and measured.The result showed that 79.41%of nutrient arteries arise from the brachial artery,8.82%from the deep brachial,the rest from the superior ulnar collateral and radial coll- ateral The average diameter of nutrient arteries is 1.16mm at the begining, and 0.67mm at the end.The average length of nutrient arteries is 2.25mm. It was found that the length and location of nutrient foramen have somet- hing to do with the origin.更多还原
