Aims and Objectives: The aims of present study are 1) to study the variations in branching pattern of the brachial plexus 2) to study the communication of median nerve with other nerves of upper limb. Materials and Methods: In present study 30 brachial plexuses from 15 well embalmed human cadavers were studied in anatomy department. In depth study was done on the communications of median with the musculocutaneous nerve and the different types were classified. Communication between ulnar nerve and median nerve was studied. Results: Out of 30 upper limbs, we found communication between musculocutaneous nerve and median nerve in 6 cases. In such cases, the communicating branch run from musculocutaneus nerve towards median nerve. Four upper limb shows communication between ulnar nerve and medial root of median nerve. Conclusion: It is concluded that knowledge of such variations is essential in evaluation of unexplained sensory and motor loss after trauma and surgical interventions to upper limb. Knowledge of these variations is important to anatomists, radiologists, anesthesiologists and surgeons.
