“…The cranial pectoral nerve, in all S. scrofa specimens, was originated from C7 and C8, similar to the reports of Ghoshal (1986c) in pigs and Souza et al (2014) in M. tridactyla. Gamba et al (2007) reported the origin of this nerve only from C7 in C. lanigera, and this was not observed in the present study.…”

“…Descriptions of Ghoshal (1986c) were 100% for pigs, Moura et al (2007) found 33% in T. tajacu and Scavone et al (2008) found 87.5% in A. paca. In four (16.6%) cases, the origin of the suprascapular nerve was from C5 and C6, similar to the findings of Scavone et al (2008) in 12.5% of A. paca specimens and Souza et al (2014) in 20% of giant anteater (Myrmecophaga tridactyla). These results differ from reports of Moura et al (2007), whom found 50% in T. tajacu, Vieira et al (2013) found 100% in M. gouazoubira, and Pinheiro et al (2013) found 100% in A. microti.…”

“…Souza et al (2014) reported that the origin of the long thoracic nerve was from C6 and C7 or C5, C6 and C7 in 60% and 40% of M. tridactyla, respectively, which was not observed in the present study. However, the origin of the long thoracic nerve at C8 and T1 was found in 25% of specimens of this work.…”

“…The origin of the median nerve was from C5, C6, C7, C8 and T1 in M. tridactyla (Souza et al, 2014) and in 58% of T. tajacu specimens (MOURA et al, 2007). Souza et al (2010) described the origin of the median nerve from C7, C8, T1 and T2 in A. australis.…”

“…Thus, the ulnar nerve has diverse origin and intraspecific variation in different species of mammals. It had origin from C7, C8 and T1 in cattle (GHOSHAL, 1986b), C8, T1 andT2 or C8 andT1 in T. tajacu (MOURA et al, 2007) and C5 and T1 in M. tridactyla (Souza et al, 2014). The ulnar nerve in S. scrofa, at the proximal third of arm, the nerve gave off the forearm caudal cutaneous nerve to supply the fascia and skin in 100% of cases, in accordance with reports of Ghoshal (1986c) in pigs.…”

ABSTRACT:The origin and distribution of the brachial plexus in wild boar (Sus scrofa), a mammal belonging to the Suidae family were studied. Twelve specimens of wild boar, which were fixed in 10% formalin solution through different points of subcutaneous, intravenous, intramuscular, and intracavitary injections, following by immersing the specimens in the same solution were used. In present study, the brachial plexus of wild boar was a set of nerve fibers formed by the ventral branches from the fifth (C5) to eighth (C8) cervical and the first (T1) thoracic spinal nerves. The subclavian nerve was originated from C5, while the suprascapular nerve had its origin from C5 to C7. The cranial and caudal subscapular nerves were predominantly originated from C6 and C7, as well was the axillary nerve. The origin of the cranial and caudal pectoral nerves was from C7-C8 and C8-T1, respectively. The musculocutaneous nerve was mostly originated from C6 and C7, while the median and radial nerves had origin from C7 to T1. The origin of the ulnar, thoracodorsal, and lateral thoracic nerves was mostly from C8 and T1, while the long thoracic nerve was predominantly originated from C7 and C8. All nerves were responsible for the innervation of scapular girdle structures, arm, forearm, thorax and abdomen. In conclusion, the origin and distribution of the brachial plexus nerves in wild boar (Sus scrofa) are similar to domestic swine rather than to other wild species described in the literature.

Twenty thoracic limbs of ten Lycalopex gymnocercus were dissected to describe origin and distribution of the nerves forming brachial plexuses. The brachial plexus resulted from the connections between the ventral branches of the last three cervical nerves (C6, C7, and C8) and first thoracic nerve (T1). These branches connected the suprascapular, subscapular, axillary, musculocutaneous, radial, median and ulnar nerves to the intrinsic musculature and connected the brachiocephalic, thoracodorsal, lateral thoracic, long thoracic, cranial pectoral and caudal pectoral nerves to the extrinsic musculature. The C7 ventral branches contribute most to the formation of the nerves (62.7%), followed by C8 (58.8%), T1 (40.0%) and C6 (24.6%). Of the 260 nerves dissected, 69.2% resulted from a combination of two or three branches, while only 30.8% originated from a single branch. The origin and innervation area of the pampas fox brachial plexus, in comparison with other domestic and wild species, were most similar to the domestic dog and wild canids from the neotropics. The results of this study can serve as a base for comparative morphofunctional analysis involving this species and development of nerve block techniques.

To elucidate the forelimb phylogeny of primates, anatomical analysis of the brachial plexus in platyrrhines is beneficial. In the present study, six brachial plexuses and the surrounding arteries of four common marmosets were dissected. In five specimens, the brachial plexus consisted of five ventral rami from the fifth cervical nerve (C5) to the first thoracic nerve (T1). In one specimen, the ventral ramus of the fourth cervical nerve joined with the brachial plexus. In five specimens, the upper trunk was composed of C5 and the sixth cervical nerve (C6). In one specimen, the ventral division of C6 merged with the ventral branch of the middle trunk to constitute the lateral cord. The seventh cervical nerve constituted the middle trunk, and the eighth cervical nerve and T1 formed the lower trunk in all specimens. The lateral cord gave rise to the musculocutaneous nerve, and the remaining component merged with the medial cord. The confluence of the lateral and medial cords immediately bifurcated into the median and ulnar nerves. These branching patterns of the musculocutaneous, median, and ulnar nerves were consistent and similar to the human counterparts. In the dorsal division, the single posterior cord as observed in the human brachial plexus was not observed. The axillary artery did not pass between the medial and lateral roots of the median nerve, and the axillary artery bifurcated into the brachial artery and the superficial brachial artery.
