Introduction: As per the medical and surgical aspects, nerve supply of upper limb is very important which is provided by brachial plexus. The aim of this study was to provide concise and relevant information about the variations in branching pattern of the brachial plexus. Material and methods: The material for the present study comprised of 40 upper limbs which belonged to 20 adult human cadavers of known sex. These were serialized and dissected according to the methods described in Cunningham’s Manual. Results:  In the present study, 35[87.50%] cases showed normal branching pattern of cords of brachial plexus and in 5[12.5%] cases, variant branching pattern was observed. Out of five variant cases, in first case we found two upper subscapular nerves, axillary nerve and lower subscapular nerve arose from posterior division of upper trunk and the nerve to latissimus dorsi arose from posterior division of middle trunk and not from posterior cord. In the second case upper subscapular nerve and axillary nerve arose from posterior division of upper trunk. In other three cases median nerve was observed to form by three roots, fibres of C7 root to ulnar nerve which are seldom visualised were observed and a communicating branch by musculocutaneous nerve to median nerve was seen. Conclusion: The findings of the present study will be of fundamental importance to the physicians, surgeons, radiologists and of course this knowledge is very important for anatomists during routine classroom dissection.
