The brachial plexus is a vital network of nerves originating from the ventral rami of C5 through spinal nerve T1 transmitting signals for the entire upper extremity to supply both motor and sensory input.1-5 After their origination at roots C5-T1, the nerves then divide into an anterior and posterior division. The anterior and posterior divisions from the brachial plexus form three cords; the lateral, medial, and posterior. Moving distally along the plexus branches that form off the root include C5/C6 for the musculocutaneous nerve and axillary nerve, with C5-T1 all contributing to the median nerve and radial nerve (1,6-13) (Figure 1).
