RESUMEN
Background: Variations of the arteries, nerves and muscles of the upper limb have both clinical and surgicalimportance. The superficial brachial artery origination from the third part of the axillary artery, communicationsbetween the musculocutaneous and median nerves, variant formation of the brachial plexus, origination of theProfunda brachii artery from the posterior circumflex humeral artery have been well documented. We describehere the other variations in the upper limbs of a male cadaver.Case Report: During our routine dissection studies on a 50year old male cadaver we encountered variations inRight upper limb.Observations: In this case we observed the axillary artery gives two terminal branches the first was the superficialbrachial artery and the second was a common trunk for the sub scapular,brachial, posterior circumflex humeral and anterior circumflex humeral arteries. Superficial brachial arterygive Radial and Ulnar arteries. Variant formations of the brachial plexus i.e., medial root of median nerveoriginate from both lateral and medial cord.Conclusion: We think that such variations should be kept in mind during surgical and diagnostic procedures.Variation in the brachial plexus medial root of median nerve originate from both lateral and medial cord mightbe of significance in diagnostic clinical neurophysiology.
