Abstract Background and aims: The median nerve is formed by the union of the medial and lateral roots from the medial [C8, Tl] and lateral cords [C5, 6, 7] of brachial plexus respectively. The nerve is formed in the axilla embracing the axillary artery. Lateral root of median nerve is a terminal branch of lateral cord and medial root of median is a terminal branch of medial cord. Variations in the formation of the median nerve are common and have been reported by various authors. The aim of this study is to observe the variations in the formation of median nerve that would help in clinical evaluation. Materials & Methods: The present study was conducted in the Department of Anatomy, Jorhat Medical College, Jorhat. Fifteen embalmed and formalin fixed cadavers were studied for variation of the median nerve. The dissections were carried out according to the Cunningham’s Manual of practical Anatomy. In total 30 upper limb specimens were used for the study. Results: Out of 30 upper limbs, in three limbs [10%] there was duplication in the formation ofthe median nerve. Among the three, two specimens were of right side and one from the left side. Conclusion: We know that brachial plexus is located in axilla and axillary region is important not only from anatomical point of view but also from various clinical aspects as well. Awareness about the many variations of brachial plexus is important in understanding nerve blocks, diagnostic imaging, trauma and surgery.

Background: Median nerve is generally formed in axilla, as one of the branch of brachial plexus. It is formed by the union of medial and lateral roots which are the branches of me­dial and lateral cord respectively. The knowledge of origin, course and area of distribution of median nerve is important for the anatomist, the neurologist and also for correction of traumatic injuries that are related to brachial plexus. The main objective of this study is to observe different variations in median nerve formation in cadavers. Methods: A descriptive cross-sectional study was conducted in 25 formalin fixed adult human ca­davers in the Department of Anatomy, KIST Medical College and Teaching Hospital, Lalitpur Ethical approval was taken. Altogether, 50 specimens were enrolled in the study by convenient sampling method. The calculation was done using Statistical Package for Social Sciences version 20 (SPSS). Results: In this study the formation of median nerve was observed to be normal in 78% of the cases. In 20% cases three roots were forming the median nerve and in 2% cases four roots were present. Among these variations in 18% cases the additional roots were observed to be given by the lateral cord of the brachial plexus. Conclusions: This study concludes that most of the median nerve forms in axilla by the union of two roots with few variations.
