AbstractObservations of the presence of the median artery, providing substantial blood supply to the hand, were conducted on 96 dissected forearms of 15 adult African females and 49 adult males. The artery has a much higher incidence (27.1%) than previously reported by any author. There is no significant difference in its occurrence between sexes, nor between right and left limbs. The artery seems to occur more often bilaterally than unilaterally. The presence of the artery is not related to age. From a theoretical standpoint it is difficult to accept that a structure present in more than 1 in 4 of individuals should be considered an 'anomaly' or a 'variant'. A different approach to description of normal human anatomy is therefore necessary--that of presenting alternative anatomical patterns of equal standing rather than a single 'normal' pattern.
