AFSHAR, Mohammad y GOLALIPOUR, Mohammad Jafar. Innervation of Muscular Axillary Arch by a Branch from Pectoral Loop. Int. J. Morphol. [online]. 2005, vol.23, n.3, pp. 279-280. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022005000300016.
The latissimus dorsi muscle is a flat and triangular muscle that covers the lumbar region and the inferior part of thorax. 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. This report deals with dissecting the axillary region of a 41 year-old male cadaver in which we observed a muscular axillary arch was innervated by a single nerve branch of pectoral loop
