Abstract

This study presents a bilateral variation in the formation of trunks of brachial plexus in a male cadaver. The right brachial plexus was composed of six roots (C4-T1) and the left brachial plexus of five roots (C5-T1). Both formed four trunks thus changing the contributions of the anterior divisions of the cervical nerves involved in the formation of the cords and the five main somatic motor nerves for the upper limb. There are very few case reports in the scientific literature on this topic; thus making the present study very relevant.
