Address for Correspondence: Dr. Suma H Y, Associate Professor, Department of Anatomy, JIPMER Academic Centre, JIPMER, Dhanvantrinagar, Puducherry-605006, India. E-Mail: [email protected] Variants in brachial plexus and its branches are significant in everyday clinical practice. During student dissection, we came across multiple variations of lateral cord, and its branches on the left arm of a male embalmed cadaver. The lateral cord was found to pierce coracobrachialis which divided into lateral root of median nerve and musculocutaneous. There was a presence of third head of biceps brachii and also communication between median and musculocutaneous nerves. This knowledge with regard to multiple variations is important in nerve blocks, compression syndromes in the axilla and arm as well as flap surgeries. Hence the present case is being reported.
