Estudo anatômico do plexo lombossacral de Tamandua tetradactyla

Abstract:  RESUMOO tamanduá-mirim (Tamandua tetradactyla) é um xenartro da família Myrmecophagidae, encontrado da Venezuela ao sul do Brasil. Estudos apontam que essa é uma das espécies de animais selvagens mais vitimadas em número de atropelamentos, e, muitas vezes, o atendimento clínico adequado aos indivíduos feridos é dificultado pela carência de informações acerca dos mesmos. Visando contribuir com o conhecimento dessa espécie, este estudo teve como objetivo descrever seu plexo lombossacral. Para tanto, foram util… Show more

“…Likewise, considering that the origin of the pudendal nerve in Spix's yellow-toothed cavy (OLIVEIRA et al, 2014) and in rock cavies (LACERDA et al, 2006) has been attributed to the ventral branches of S 2 and S 3 , we found three specimens of the red-rumped agouti where the origin of this nerve was only from S 3 and two where this nerve originated from S 3 and S 4 . This latter finding is consistent with what has been reported for the collared anteater (CARDOSO et al, 2013).…”

“…The origin of this plexus has also been reported in other mammals. For example, the plexus originates from L 4 L 5 −S 1 S 2 in the ocelot (LOPES et al, 2012), T 18 −L 3 and S 1 −S 5 in the collared anteater (CARDOSO et al, 2013), L 1 to S 3 in the fur seal (CASTRO et al, 2009), L 3 − L 7 and S 1 −S 3 in the dog (GETTY, 1981), L 4 −L 7 and S 1 −S 3 in the cat (GETTY, 1981), and L 4 −L 7 and S 1 −S 3 in the rabbit (MCLAUGHLIN; CHIASSON, 1987); the latter two results are similar to what we observed in the red-rumped agouti.…”

“…Aydin (2009) observed that in the porcupine (Hystrix cristata), the femoral nerve originated mainly from the ventral branches L2 and L3, with contributions from T15 and L1, different from that observed in the present investigation. Cardoso et al (2013) studied the composition of the lumbosacral plexus of the collared anteater (Tamandua tetradactyla) and observed the contribution of lumbar branches (L1-L3) in all studied specimens, and also the participation of T18 in 75% of them in the formation of the femoral nerve. This formation resembles that of the porcupine (T15, L1-L3) (Aydin), and differs from that observed in rabbits of this study.…”

“…Souza et al (2013) studied the branches of the femoral nerves in the giant anteater (Myrmecophaga tridactyla) and found that the origins in the right and left antimeres occurred from ventral branches of the first, second and third lumbar spinal nerves. However, Cruz et al (2014), also analyzing the giant anteater (Myrmecophaga tridactyla), observed participation of thoracic segments (T15, T16) in the formation of the femoral nerve.…”
