Abstract

Introduction: The brachial plexus is a complex network located in the neck and axilla region. Various Variations of the brachial plexus have been reported, which are clinically significant. Objective: Given that Variations of the brachial plexus, especially involving the musculocutaneous and median nerves, are relatively common, the aim of this study is to report an anatomical Variation of the brachial plexus related to the musculocutaneous and median nerves. Methods: In this study, during the dissection of a 71-year-old male cadaver in the anatomy hall of the medical school at Torbat Heydarieh University of Medical Sciences, a Variation in the median nerve was observed. In this case, the median nerve, which normally separates from the lateral and medial cords and descends in the arm to the cubital fossa without any connection to other nerves, after the coracobrachialis muscle was found to be connected to the musculocutaneous nerve. Results: A comprehensive understanding of Variations in upper limb nerves can be crucial in interpreting and diagnosing various types of surgeries, especially those related to the reconstruction and rehabilitation of the brachial plexus. Conclusion: It can be concluded that population areas such as urban and rural centers are vulnerable to air pollution in terms of social vulnerability and Nimroz and Hamoon counties have the lowest social vulnerability.
