ABSTRACT
This paper aims to describe the origin of the brachial plexus of 12 iguanas, male and female, which were donated already dead by the Wild Animal Screening Center and Independent Company of Highway and Environmental Police of the Araguaína, Tocantins State, to Veterinary Anatomy Laboratory of Federal University of Tocantins, Araguaína campus These animals were fixed by intramuscular injections of aqueous 10% formalin. It was made a parallel incision to dorsal midline from the skull to the caudal ribs. It was pulled all the epiaxial muscles eight ribs, the periosteum, exposing and individualizing the ventral rami of spinal nerves that make up the brachial plexus. The ventral rami of spinal nerves C6, C7, C8, T1 and T2 form the brachial plexus in 12 iguanas. In 41.6% of cases, the branches involved were C6, C7, C8 and T1; in 33.4%, the branches C6, C7, C8, T1 and T2; 16.6% the branches C7, C8, T1 and T2 and in 8.4%, the branches C7, C8 and T1. The branches ventral C7, C8 and T1 formed three trunks and C6 and T2, when present, consisted of nervous fillet. There was variation in number of vertebrae in Iguana iguana iguana which caused oscillations in anastomoses, that constitute the nerves of brachial plexus. The axillary, subscapular, cutaneous, pectoral, coracobrachialis, radial, median, ulnar, thoracodorsal nerves are the main nerves that constitute the brachial plexus in iguanas.
RESUMO
Esse trabalho tem como objetivo descrever a origem do plexo braquial de 12 iguanas, machos e fêmeas, doados mortos pelo Centro de Triagem de Animais Silvestres e Companhia Independente de Polícia Rodoviária e Ambiental ­ Araguaína ­ Tocantins, ao Laboratório de Anatomia da Universidade Federal do Tocantins, campus de Araguaína. Fixou-se os animais com injeções intramusculares de solução aquosa de formalina a 10%. Realizou-se uma incisão paralela a linha mediana dorsal desde o crânio até a região caudal das costelas. Retirou toda a musculatura epiaxial, oito costelas, o periósteo, expondo e individualizando os ramos ventrais dos nervos espinhais que compõem o plexo braquial. Os ramos ventrais dos nervos espinhais C6, C7, C8, T1 e T2 formam o plexo braquial nas 12 iguanas. Em 41,6% dos casos, os ramos envolvidos foram C6, C7, C8 e T1; em 33,4%, os ramos C6, C7, C8, T1 e T2; em 16,6 % os ramos C7, C8, T1 e T2 e em 8,4%, os ramos C7, C8 e T1. Dos ramos ventrais C7, C8 e T1 formavam três troncos e C6 e T2, quando presentes, consistiam de filetes nervosos. Houve variação no número de vértebras na Iguana iguana iguana, que provocaram oscilações nas anastomoses que constituem os nervos do plexo braquial nas iguanas. Os nervos axillar, subscapular, cutâneo, peitoral, coracobraquial, radial, mediano, ulnar e toracodorsal são os principais nervos que constituem o plexo braquial nas iguanas.
