A Cadaveric Study on Anatomical Variations of Median Nerve Formation: Embryological and Clinical Correlations

Volume : IV, Issue : IV, April - 2015

The median nerve is formed lateral to the third part of the axillary artery by the union of the lateral and medial

roots originating from the lateral and medial cords of the achial plexus.

Variations of median nerve, musculocutaneous nerve and their communicating anches are of interest for anatomists and surgeons. These

variations may be vulnerable to damage in surgical procedures.

The median nerve is one of the commonest nerve showing variations from the level of its formation to its termination. This is an important

region where anatomists, radiologists, anesthetist, plastic surgeon and oncologist land up with problems more frequently, if they are not aware

of these variations. We studied the variation in the formation of the median nerve in 40 upper limbs of formalin preserved cadavers at the

department of Anatomy, MGM Medical College, Navi Mumbai, India.
