| Abstract | Introduction: The brachial plexus, a complex network of nerves, innervates to the upper limbs. Variation in the course of the nerves in the upper limb is common. Case Presentation: This paper describes two cases of upper limb variations in a cadaver dissected at Lorestan University of Medical Sciences. In the first variation, the median nerve in the arm has a different route, so that the median moves deep into the brachialis muscle. In the latter case, after piercing the coracobrachialis muscle a musculocutaneous nerve exists between the brachialis and biceps and goes to the lateral region of the forearm. This is known as the lateral cutaneous nerve of the forearm nerve, and innervates the skin of the lateral part of the forearm and the dorsal part of the hand. Conclusions: Because of the possibility of damage to the brachial plexus branches is high in upper limb injuries and surgeries, full knowledge of normal anatomy and variations of these branches is essential for orthopedic specialists, neurosurgeons, radiologists, and anatomists. | en |
