Sixty-two forearms from 36 cadavers of South Africans of European extraction were dissected. The frequency of the median artery per forearm was 27.4%. There was neither bilateral difference nor sexual dimorphism in the incidence of the artery. These findings compare well with a previous study of black South Africans (Henneberg & George, 1992) where frequency per forearm was 27.1%. Our findings are much higher than those of earlier studies. This discrepancy may be explained either by differences in the thoroughness of the observations or regional variation, or by the occurrence of a secular trend in the development of vasculature.
对36具欧洲裔南非人尸体的62条前臂进行了解剖。每条前臂正中动脉的出现频率为27.4%。该动脉的发生率在双侧及性别上均无差异。这些发现与之前对南非黑人的研究（Henneberg & George，1992）结果相当，在该研究中每条前臂的出现频率为27.1%。我们的发现远高于早期研究结果。这种差异可能是由于观察的彻底程度或区域差异，或者是由于脉管系统发育中出现的长期趋势所致。
