“…The data on the topography and length of the final portion of the spinal cord have been described in domestic Evans and De Lahunta, 2010;Martinez-Pereira and Zancan, 2015) and wild carnivores (Carvalho et al, 2003;Machado et al, 2009;Brıgida et al, 2010;Gregores et al, 2010;Branco et al, 2013). Considering only the Canidae family, the dog (Santiago, 1974;Evans and De Lahunta, 2010;Fletcher, 2013) and some species of wild canids, as Chrysocyon brachiurus (Machado et al, 2002), Atelocynus microtis (Saldanha et al, 2011), Lycalopex gymnocercus (Souza Junior et al, 2014), and a one exemplar of Cerdocyon thous (Pinheiro et al, 2011) had described the topography of this region.…”

“…The topography of the caudal end of the spinal cord (intumescentia lumbalis and conus medullaris) and anatomy of lumbosacral plexus (LSP) are largely described in domestic animals (Miller et al, 1964;Getty, 1975;Dyce et al, 2009;Martinez-Pereira and Zancan, 2015), and various wild carnivores have described these structures (Carvalho et al, 2003;Machado et al, 2009;Castro et al, 2009;Brıgida et al, 2010;Gregores et al, 2010;Lopes et al, 2012;Branco et al, 2013;Medina et al, 2014). However, are few studies about the caudal end of spinal cord and LSP in wild canids, as C. thous and P. gymnocercus.…”

In this study, the spinal nerves that constitute the lumbosacral plexus (LSP) were dissected in two species of South American wild canids (pampas fox-Pseudalopex gymnocercus, and crab-eating fox-Cerdocyon thous). The nerves origin and distribution in the pelvic limb were examined and compared with the LSP model of the dog described in the literature. The LSP was formed by whole ventral branches of L5 at L7 and S1, and a contribution of a one branch from S2, divided in three trunks. The trunk formed by union from L5-6 and S1 was divided into the cranial (cutaneus femoris lateralis nerve) medial (femoralis nerve) and lateral branches (obturatorius nerve). At the caudal part of the plexus, a thick branch, the ischiadicus plexus, was formed by contributions from L6-7 and S1-2. This root gives rise to the nerve branches which was disseminated to the pelvic limb (nerves gluteus cranial and gluteus caudal, cutaneus femoris caudalis and ischiadicus). The ischiadicus nerve was divided into fibularis communis and tibialis nerves. The tibialis nerve emits the cutaneus surae caudalis. The fibularis communis emits the cutaneus surae lateralis, fibularis superficialis and fibularis profundus. The pudendus nerve arises from S2 with contributions of one branch L7-S1 and one ramus of the cutaneus femoris lateralis. Still, one branch of S2 joins with S3 to form the rectales caudales nerve. These data provides an important anatomical knowledge of a two canid species of South American fauna, besides providing the effective surgical and clinical care of these animals.

Background:The common marmoset (Callithrix jacchus) belongs to the family Cebidae and Subfamily Callitrichinae, a group formed by the smallest anthropoid primates. It is a very common species and adapts easily to captivity, an aspect that encourages the clandestine capture of these animals and makes them susceptible to wounds resulting from clandestine rearing and inadequate management, so that studies to understand the species are extremely important. With the objective of supplying anatomic bases for the practice of epidural anesthetic, data were studied regarding the topography of the common marmoset (Callithrix jacchus). Materials, Methods & Results:The study was carried out at the Laboratory of Veterinary Anatomy at the Federal University of Campina Grande (UFCG), PA, Brazil. Ten adult common marmosets (Callithrix jacchus) were used, 5 males and 5 females, with different causes of death. A round workbench magnifying lamp was used to better visualize the dissecation field. Number 15 scalpel blades, surgical pincers and scissors were used to dissect. After fixing in 10% formaldehyde aqueous solution, dissecation was made along the mid dorsal line, from the cranial thoracic region to the tail base to expose the vertebral arches and measure the intervertebral spaces. The vertebral arches were removed, and consequently the spinal dura mater was exposed, that was sectioned longitudinally to expose the spinal chord and identify the lumbar intumescence, the conus medullaris and the cauda equina. The length of the conus medullaris was measured and its skeletopy was established. The body and tail length data were submitted to analysis of variance and the means were compared by the Tukey test at 5% probability. The mean value of the conus medullaris length was 1.4 cm, while the anatomic location of the conus medullaris varied slightly among the animals, but did not pass the limit between L3 for the base and L6 for the apex. On average, the lumbosacral space measured 3.03 mm, that is sufficient to introduce a needle similar to that used in syringes for insulin injection. The results of this study suggest the lumbarsacral space as location for epidural anesthetic application in Callithrix jacchus, at a safe point situated in the center of an isosceles triangle, the base of which is found when a line is drawn from one side of the pelvis to the other, and the apex corresponds the spinal process of the first sacral vertebra. Discussion: The anatomic location of the conus medullaris is different compared to two other primate species, the red handed tamarin (Saguinus midas), in which the cone base was registered at L4 and the apex at S2, and the common squirrel monkey (Saimiri sciureus) where the conus medullaris base occurs at L7-8 and the apex at S3 or Cc1. However, some similarities with other mammal groups were observed in the conus medullaris topography, such as the black-striped capuchin (Sapajus libidinosus). The mean conus medullaris length of the species Callithrix jacchus of 1.4 cm was close to that observ...
