Sex‐related Macrostructural Organization of the Deer's Brachial Plexus

Abstract: We describe the morphological organization of the deer brachial plexus in order to supply data to veterinary neuroclinics and anaesthesiology. The deer (Mazama gouazoubira) brachial plexus is composed of four roots: three cervical (C6, C7 and C8) and one thoracic (T1). Within each sex group, no variations are observed between the left and the right brachial plexus, though sex-related differences are seen especially in its origin. The origin of axillary and radial nerves was: C6, C7, C8 and T1 in males and C8-T… Show more

“…In the present study, there were no found differences in the anatomical features of the studied nerves related to the body conformation, or the side of the body (left and right) in the evaluated cadavers. Similar results have been described in a study that evaluated the anatomical features of the brachial plexus in deers ( Mazama gouazoubira ; Melo et al., ). Contrarily, in a study performed in capybaras ( Hydrochaeris hydrochaeris ), Fioretto et al.…”

“…The cranial bound of the brachial plexus of the M. tridactyla differ from that of other mammals, such as lemurs (Miller, ), platypus (Koizumi and Sakai, ), gorillas, chimpanzees and gibbon (Koizumi and Sakai, ), capybara (Fioretto et al., ) and collared peccary (Moura et al., ), whose plexuses start with C4, and from domestic animals (Getty, ; Dyce et al., ; König and Liebich, ), rock cavy (Santana et al., ), South American fur seal (Souza et al., ), collared peccary (Moura et al., ), chinchillas (Gamba et al., ), deers (Melo et al., ), where brachial plexus originates from C6. The involvement of C3 in the brachial plexus composition is less frequent, being reported in monotremes (Koizumi and Sakai, ).…”

“…Allam et al (1952) determinaram que esta também foi a formação mais frequente do plexo braquial em cães domésticos correspondendo a 58,62% de 58 plexos dissecados, ainda que a contribuição de C5 e/ ou T2 tenham sido comumente observadas. Esta formação do plexo braquial também foi verificada em Connochaetes sp., Camelus sp., Coendou prehensilis (Paterson, 1887), felinos domésticos (Ghoshal 1986b, Aubert et al 2004, ovinos, caprinos (Goshal 1986a), Capricornis crispus (Atoji et al 1987), Myocastor coypus ), Chinchilla lanigera (Gamba et al 2007), Arctocephalus australis (Souza et al 2010), em Mazama gouazoubira (Melo et al 2007, Prestes et al 2013, Vieira et al 2013) e em Atelocynus microtis (Pinheiro et al 2013). Mesmo sem especificar a espécie, Swan (1864) apud Paterson (1887) refere que em "raposas" apenas quatro ramos ventrais formaram o plexo braquial sem especificar quais seriam, mas supomos serem os mesmos encontrados em C. thous, visto que em todos os mamíferos levantados C6, C7, C8 e T1 formam o plexo.…”

“…Em um estudo com 200 plexos de fetos humanos abortados os autores relataram que apenas 46,5% detinham uma organização considerada típica, enquanto 53,5% demonstraram uma variação significativa em relação ao padrão mais esperado (Uysal et al 2003). Melo et al (2007) relataram que no veado catingueiro a origem do plexo braquial dos machos era mais cranial e a distribuição mais complexa do que nas fêmeas. A amostragem de C. thous utilizada neste estudo foi predominantemente de fêmeas (80%), como reflexo do maior número de atropelamentos de indivíduos do sexo feminino desta espécie na região geográfica do estudo.…”
