Median artery
When the median artery prevalence reaches 50% or more, it should not be considered as a variant, but as a ‘normal’ human structure.[3] "This increase could have resulted from mutations of genes involved in median artery development or health problems in mothers during pregnancy, or both.If this trend continues, a majority of people will have median artery of the forearm by 2100.In a deep wrist laceration, such as from a suicide attempt, the median artery may be incised, risking exsanguination.An individual who does not have a median artery appears to suffer no ill effects.
