What about the other roots?[edit]

If the origin of the subscapular nerve is the posterior cord of the brachial plexus, and the posterior cord is formed by the posterior division of the three trunks (superior, medial and inferior) which in turn are formed by the five roots of the brachial plexus, how come the superior subscapular (or the thoracodorsal and inferior subscapular for that matter) are not said to be originated from all of the five roots? — Preceding unsigned comment added by 200.202.249.82 (talk) 00:13, 30 June 2013 (UTC)[reply]
