study of the variations in the main arterial branching patterns of the human upper limb

Abstract

In anatomy, “Normal” means “within the normal range of variation” (Moore and Dalley 2006). This means that normality embraces a range of morphologies and includes those that are commonly found, and others called variations because they are less frequent but not considered abnormal (Sañudo et al. 2003). Each human body possesses a unique configuration and has its complement of variations (Willan and Humpherson 1999). Little is known about such variability of human anatomy. A recent compendium of anatomical variation (Bergman et al. 2003) testified to the heterogeneity of our knowledge in this regard. A basic law of vascular anatomy is that the only thing which remains constant is its variabi 1993). The variation in the vascular pattern is more frequently observed in the living than in among people of different races (Uzun and Seelig 2000). Some arteries have more variation al. 1953; Keen 1961; Tountas and Bergman 1993), the most frequent are those involving a s continues into the forearm and have therefore attracted more attention than variations affect (Rodríguez-Niedenführ et al. 2003).
