Abstract
Dorsal scapular nerve takes its origin from the posterior aspect of C5 root. It then descends downwards and pierces the scalenus medius and passes backward, downward and laterally. It lies beneath the prevertebral fascia in the occipital triangle, it then disappears beneath the levator scapulae muscle to supply the rhomboids muscle. Dorsal scapular syndrome presents as an abnormal movement of the shoulder joint even though reduced movement. In this study we have reported the double origin of Dorsal scapular nerve in this manner is not so commonly found and the brachial plexus in our cadaver is prefixed type.
