Arterial, neural and muscular variations in the upper limb

Abstract

During our routine dissection studies we observed arterial, neural and muscular variations in the upper limbs of an adult male cadaver. In this case we observed the superficial brachial artery origination from the third part of the axillary artery, communications between the musculocutaneous and median nerves, variant formation of the brachial plexus, origination of the profunda brachii artery from the posterior circumflex humeral artery and supernumerary tendons of the abductor pollicis longus muscle. We think that such variations should be kept in mind during surgical and diagnostic procedures.
