Variant Formation And Distribution Of Median Nerve

During routine cadaveric dissection while teaching undergraduate medical students, the median nerve on theleft upper limb of a 60 year old female cadaver showed presence of an accessory lateral root arising from lateralcord of brachial plexus.It also pierced brachialis muscle in the arm before reaching cubital fossa. Knowledge ofthese variations is helpful in evaluating nerve injury and preventing complications during anaesthetic andsurgical procedures in the axilla.
