The majority of the glenohumeral joint is innervated by the suprascapular nerve (C5-C6; originates from upper trunk of brachial plexus) and the axillary nerve (C5-C6; originates from posterior cord of brachial plexus).
Dorsal divisions of upper and lower trunks united to form posterior cord of brachial plexus while ventral division of upper and lower trunks continued as lateral and medial cord respectively (Fig.
This muscle supplied by thoracodorsal nerve(C6, C7,C8), a branch of posterior cord of brachial plexus. Many reports showed that a muscular axillary arch, flat muscle arising from lateral border of latissimus dorsi, may be seen in 7% of the population, but there is little information about the innervation of this part.
