Variations in formation of median nerve by more than two roots are relatively uncommon as compared to other variations. During routine dissection for undergraduates, we observed two variations in the formation of median nerve. In one case unilateral variation was observed in 40 year old male cadaver in left axillary region. Here the formation of median nerve was by four roots. Three roots coming from lateral cord joined single root from medial cord leading to median nerve formation. In other case formation was by three roots, two roots from lateral cord and one from medial cord. This variation was present bilaterally. However, in both the cadavers the distribution of the anomalous median nerve was normal in arm, forearm and palm. Presence of such additional roots must be kept in mind during surgery to avoid their injury. It can also explain some unusual clinical symptoms.
