Resumo

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.
