INZUNZA, Oscar et al. Panniculus carnosus, Vestigial Remanents in the Axillary Región. Int. J. Morphol. [online]. 2008, vol.26, n.4, pp.841-844. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000400010.
The anatomical variations of the muscular elements of the axillary región are infrequent and, generally, they are forgotten in modern texts of anatomy. Nevertheless, when they exist, they present a serious obstacle for the surgeon, since they alter the anatomical landmarks of reference for the approach to important neural and vascular elements of the región. Since the 19th century some authors have described a variety of small muscular fascicles originated in the "panniculus carnosus", that are arranged in relation to neurovasculares elements of the axila. In this occasion we present a finding performed in a corpse, male sex, dissected in the Department of Anatomy of the School of Medicine of the Pontificia Universidad Católica de Chile. In the right axillary región, a muscular fascicle is observed that extends from the coracoid process, arranged in front of the subscapularis muscle, and passing behind the neurovascular elements of the axila. In its course, this fascicle takes cióse relation with the axillary nerve and with the distal portion of the subscapular artery. This aberrant fascicle ends as an aponeurotic expansión, arranged ventral to the tendón of the latissimus dorsi muscle, which melts with the axillary fascia.
