Abstract Background Brachial Plexus innervates the upper limb. As it is the point of formation of many nerves variations are common. Knowledge of these is important to anatomists radiologists anesthesiologists and surgeons. The presence of anatomical variations of the peripheral nervous system is often used to explain unexpected clinical signs and symptoms. Case Presentation On routine dissection of an embalmed 57 year old male cadaver variations were found in the formation of divisions and cords of the Brachial Plexus of the right side. Some previously unreported findings observed were direct branches to the muscles Pectoralis Minor and Latissimus dorsi from C6 innervation of deltoid by C6 and C7 roots and the origin of lateral pectoral nerve from the posterior division of upper trunk. The median nerve was present lateral to axillary artery. The left side brachial plexus was also inspected and found to have normal anatomy. Conclusion The probable cause .
