Neural and Arterial Variations in the Right Upper Limb of a Single Cadaver- A Case Report

Abstract

Background: During routine undergraduate dissection of a 43 years old male cadaver some important neural and arterial anatomic variations were seen in a single right upper limb in the form of double medial roots of median nerve and superficial brachial artery. Observation: During routine dissection of a 43-year-old male cadaver, some important neural and arterial anatomical variations were observed in a single right upper limb in the form of double medial roots of the median nerve and superficial brachial artery. The median nerve was formed in axilla by the union of one lateral and two medial roots on lateral side of axillary artery. The brachial artery which crossed the median nerve superficially from the medial to the lateral side, in the middle of the arm, continued as the superficial brachial artery. The variations were observed and photographed. Conclusion: The knowledge of such variations is however not only desirable, but also essential as these have important influences on the predisposition to illness, clinical examination, investigations and patient management, including operative surgery.
