“…The current case presents a unique variation in the branching pattern of the SBA. This is a relatively rare variation of the SBA, found in 0.1-12.2% of patients (Carroll et al, 2021). In the early embryo, the superficial and deep brachial arteries anastomose at various levels of the arm, including a more proximal level and a more distal level (Singer, 2005;Yoshinaga et al, 2003).…”

“…In anatomical studies on human brachial plexuses itself, single-corded brachial plexuses (C-type brachial plexus) [19] and their relationship with the superficial brachial artery have been studied [9,10,11]; however, in these sample series, it is unknown whether they have normal or aberrant thoracolumbar counts and formulae. Regardless of the thoracolumbar counts in our material series, all main root components of the brachial plexus involved only the 5-9 th spinal nerves, with a small contribution by the 4 th (17/20, 85.0%) and 10 th nerves (4/20, 20.0%).…”

“…Regardless of the thoracolumbar counts in our material series, all main root components of the brachial plexus involved only the 5-9 th spinal nerves, with a small contribution by the 4 th (17/20, 85.0%) and 10 th nerves (4/20, 20.0%). In studies using larger samples with uncertain vertebral formulae, the main human brachial plexus roots are also composed of the 5-9 th spinal nerves (C5-T1) [9,10,26]. Hirasawa (1931) also identified a small contribution from C3 (1.0%), C4 (30.0%), and T2 (16.5%) to the brachial plexus on 200 sides [19].…”

Background: Experimental evidences identified that thoracolumbar mutants caused by Hox genes 7-10 mutants also involve a craniocaudal shift and/or the addition or reduction of segments of the limb plexus roots. This study investigated whether the theoretical concomitant shift of the brachial plexus roots in human different thoracolumbar counts is shared as confirmed in those of the human lumbosacral plexus. Material and methods:The phenotypic morphology of the brachial plexus and its arterial interaction on 20 sides of 10 atypical human thoracolumbar counts out of the 354 sides of the 177 cadavers, were compared with those of 52 sides of 26 cases in a typical human vertebral formula (7C_12T_5L_5S).Results: Regardless of the course and branching patterns of the axillary artery, our results showed that the main brachial plexus roots were composed of only five segments of the 5 th -9 th spinal nerves, with small contributions from the 4 th and/or 10 th nerves. This root composition is identical to a typical human thoracolumbar formula, and therefore, neither a craniocaudal shift nor additional/reduced main roots occurred in our thoracolumbar variants. Conclusions:Unlike the concomitant shift of the lumbosacral plexus roots, our present cases suggest that the phenotypic morphology of the human brachial plexus may be less likely to 1 show theoretical craniocaudal shifts, further data on the root changes in different vertebral formulae are needed for its accurate validation.

“…Performing surgical manipulations and interventions on myofascial and neurovascular formations and bundles of the upper limb, and especially in the anterior brachial region, in human fetuses and newborns requires comprehensive knowledge of their topographical and anatomical features 1 . The anterior brachial region is characterized by age-related and individual anatomical variability of neurovascular bundles, which is a frequent cause of complications during operations [2][3][4][5][6] .…”

Variabilité anatomique foetale des muscles et des faisceaux neurovasculaires de la région brachiale antérieureIntrodu ction. La réalisation de manipulations chirurgicales et d'interventions opératoires sur des faisceaux neurovasculaires situés dans la région brachiale antérieure de foetus et de nouveau-nés humains nécessite une connaissance approfondie de leurs caractéristiques topographiques et anatomiques. L'objectif de l'étude. Établir les particularités de la topographie foetale des nerfs et des vaisseaux dans la région du muscle brachial antérieur. Matériaux et méthodes. L'étude été réalisée sur 32 sujets de foetus humains de 4 à 8 mois de 81,0 à 310,0 mm de longueur couronne-croupe (CRL) en utilisant la dissection macro microscopique, les injections vasculaires et la morphométrie.Résultats. Chez les foetus humains, les sources principales et supplémentaires d'approvisionnement en sang musculaire et d'innervation de la région brachiale antérieure sont décrites. De 2 à 4 branches du nerf musculo-cutané participent à l'innervation des muscles coraco brachial et brachial, ainsi que du muscle
