“…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, ).…”

Ten forelimbs of five Myrmecophaga tridactyla were examined to study the anatomy of the brachial plexus. The brachial plexuses of the M. tridactyla observed in the present study were formed by the ventral rami of the last four cervical spinal nerves, C5 through C8, and the first thoracic spinal nerve, T1. These primary roots joined to form two trunks: a cranial trunk comprising ventral rami from C5-C7 and a caudal trunk receiving ventral rami from C8-T1. The nerves originated from these trunks and their most constant arrangement were as follows: suprascapular (C5-C7), subscapular (C5-C7), cranial pectoral (C5-C8), caudal pectoral (C8-T1), axillary (C5-C7), musculocutaneous (C5-C7), radial (C5-T1), median (C5-T1), ulnar (C5-T1), thoracodorsal (C5-C8), lateral thoracic (C7-T1) and long thoracic (C6-C7). In general, the brachial plexus in the M. tridactyla is similar to the plexuses in mammals, but the number of rami contributing to the formation of each nerve in the M. tridactyla was found to be larger than those of most mammals. This feature may be related to the very distinctive anatomical specializations of the forelimb of the anteaters.

“…Entretanto, Allam et al (1952) em 58 cães verificaram a participação do ramo ventral de C5 em 24,09%, e Bailey et al (1982) mais. Este ramo também foi observado em 35% na formação dos plexos braquiais de 07 mocós (Santana et al 2003) e em estudos realizados em porquinho da índia por Cooper & Schiller (1975).…”

“…Dentre os ramos que sempre participavam da formação do plexo braquial em catetos, o ramo ventral de C7 correspondia a maior raiz, a qual sempre estabelecia uma calibrosa ligação com a raiz proveniente de C8, formando um tronco com contribuição de T1, do qual derivavam nervos destinados à musculatura da região caudomedial dos membros torácico e parede lateral do tórax, o mesmo foi observado em mocós (Santana et al 2003). Os ramos ventrais C8 e T1 estão ligados ao tronco simpático por meio de um fino ramo comunicante cinzento, que fornece fibras do sistema nervoso autônomo para o plexo, de modo semelhante ao que ocorre com os ramos de C7, C8 e T1, nos eqüinos (Ghoshal 1986).…”

Análise comparativa da origem do plexo branquial de catetos (Tayassu tajacu)

et al. 2007

View full text Add to dashboard Cite

O cateto (Tayassu tajacu) pertence à familia Tayassui-dae e é caracterizado por "colar" de pêlos brancos ao redor do pescoço que se estende bilateralmente cranialmente aos ombros. Pode ser encontrado do sudoeste dos Estados Unidos da América até a Argentina. Na literatura verificou-se a falta de dados a respeito da anatomia funcional do cateto especialmente trabalhos que envolvem a anatomia do plexo braquial. Visando elucidar o comportamento do plexo braquial do cateto e com a finalidade de contribuir para o desenvolvimento da anatomia comparada, realizou-se esta pesquisa. Utilizou-se 30 animais de idades diferentes (13 fêmeas e 17 machos) provenientes do Centro de Multiplicação de Animais Silvestres, Universidade Federal Rural do Semi-árido, Mossoró, Rio Grande do Norte. Após o abate, realizou-se a dissecação bilateral dos plexos braquiais e registraram-se os resultados através de desenhos esquemáticos e as disposições agrupadas em tabelas para subseqüente análise estatística e obtidas as freqüências percentuais. Observou-se que o plexo braquial de catetos é resultado das comunicações estabelecidas, principalmente, entre os ramos ventrais dos três últimos nervos espinhais cervicais (C6, C7 e C8) e dos dois primeiros nervos espinhais torácicos (T1 e T2), tendo uma contribuição do quarto e quinto nervos cervicais em 16,67% e 50,00% dos casos, respectivamente. Em 40,00% das dissecações a formação do plexo, mais freqüente, foi do tipo C6, C7, C8, T1 e T2. Os principais nervos derivados do plexo braquial dos catetos e suas respectivas origens foram: nervo supraescapular (C6 e C7), nervo subscapular (C5, C6 e C7 ou C6 e C7), nervo axilar (C6 e C7), nervo músculocutâneo (C7 e C8), nervo mediano (C7, C8, T1 e T2), nervo ulnar (C8, T1 e T2), nervo radial (C8, T1 e T2), nervos peitorais craniais (C7) e caudais (C7 e C8), nervo toracodorsal (C6, C7 e C8), nervo torácico longo (C7 e C8) e nervo torácico lateral (C8, T1 e T2).

“…Their geodistribution is limited to the Biome Caatinga in the Brazilian Northeast (Thomaz et al, ), where there are granite rocks that serve as refuges when threatened by predators (Zogno, Miglino, & Oliveira, ). They are adapted to the conditions of heat, scarcity of food and water, especially in long dry periods (Santana et al, ). They have habit of going out in the afternoon or in the evening in search of leaves, shoots, branches, fruits, tree barks, roots, and tubers of the vegetation that constitute their diet (Oliveira et al, ; Oliveira, Gonçalves, & Bonvicino, ).…”

This research describes for the first time the complete morphology of the digestive apparatus of rock cavies. Dissection, light microscopy, and scanning electron microscopy were performed. The oral cavity has: the hard palate without palatine wrinkles and the soft palate; the tongue composed by striated musculature, with presence of vallate, foliated, and fungiform papillae with taste buds and filiform papillae with mechanical function; and, 20 teeth of the hypsodonts type. Esophagus, stomach, small intestine (duodenum, jejunum, and ileum), and the large intestine (cecum, colon, and rectum) are found. The anus is present at the end of the alimentary channel. Organs of digestive tube are composed by four tunics: mucosa, submucosa, muscular, and serosa. The duodenum, jejunum and ileum have villi. Jejunum, ileum and cecum present Lieberkühn crypts. The cecum has mucous glands. Colon and rectum are folded and have goblet cells. Anus presents sebaceous glands. As associated glands it is found the liver with six lobes and gallbladder; a lobulated pancreas; and a pair of each major salivary gland (parotid, mandibular, and sublingual). Parotid glands have serous acini and mandibular and sublingual glands have mucous acini. Pancreas has adenomers. The liver has hepatocytes and portal vein, hepatic artery, and bile duct (portal triad), separated by sinusoids. It is concluded that the digestive apparatus of the rock cavy has variations in the dentition, lingual papillae, and acini of the salivary glands when compared to other rodents. Other variations refer to the well‐developed cecum characteristic of herbivorous behavior.
