Abstract: Variations in the morphology of biceps brachii muscle and its motor nerve , the musculocutaneous nerve have been studied extensively. The infero medial type of accessory third head of biceps and anastomoses between musculocutaneous and median nerve are the most common and frequent of all the reported variations. Studies describing existence of the said anomalies are few in literature. The aim of this study is to analyse the correlation between the most common reported anomaly of biceps and its motor nerve.
