Anatomical and radiographic appearance of the capuchin monkey thoracic cavity (Cebus apella)

Abstract

Pesq. Vet. Bras. 32(12):1345-1350, dezembro 2012 1345 RESUMO.-[Aparência anatômica e radiográϐica da cavidade torácica do macaco-prego (Cebus apella).] O macaco-prego é muito comum tanto no norte, quanto no sul da The capuchin monkey is widespread both north and south of the Legal Amazon and in the Brazilian cerrado. Ten clinically healthy capuchin monkeys were submitted to an anatomical and radiographic study of their thoracic cavities. The radiographic evaluation allowed the description of biometric values associated with the cardiac silhouette and thoracic structures. Application of the VHS (vertebral heart size) method showed positive correlation (P<0.05) with depth of the thoracic cavity, as well as between the body length of vertebrae T 3 , T 4 , T 5 and T 6 and the cardiac length and width. The lung ϐields showed a diffuse interstitial pattern, more visible in the caudal lung lobes and a bronchial pattern in the middle and cranial lung lobes. The radiographic examination allowed preliminary inferences to be made concerning the syntopy of the thoracic structures and modiϐication of the pulmonary patterns and cardiac anatomy for the capuchin monkey.INDEX TERMS: Capuchin monkey, brown capuchin, Cebus apella, radiography, wild animals, Amazon.Amazônia Legal e no cerrado brasileiro. Dez macacos-prego clinicamente saudáveis foram submetidos a um estudo anatômico e radiográϐico de suas cavidades torácicas. A avaliação radiográϐica permitiu a descrição de valores biométricos associados à silhueta cardíaca e estruturas torá-cicas. A aplicação do método de VHS (vertebral heart size) demonstrou correlação positiva (P <0,05) com a profundidade da cavidade torácica, assim como entre o comprimento do corpo de vértebras T3, T4, T5 e T6 e do comprimento e largura cardíaca. Os campos pulmonares apresentaram padrão intersticial difuso, mais visível nos lobos pulmonares caudais e um padrão brônquial em lobo pulmonar médio e cranial. O exame radiográϐico permitiu inferências preliminares a serem realizadas no âmbito da sintopia das estruturas torácicas e de modiϐicação dos padrões pulmonares e anatomia cardíaca para o macaco-prego.

CARDIOTHORACIC RATIO AND VERTEBRAL HEART SCALE IN CLINICALLY NORMAL BLACK-RUMPED AGOUTIS (DASYPROCTA PRYMNOLOPHA, WAGLER 1831)

“…25, 26 Recently, a positive correlation was described between the thoracic cavity length and the vertebral bodies, suggesting the use of these measurements to quantify increases in heart size in blackrumped agoutis and capuchin monkeys. 1,9 Similarly, the measurements of the length of the T4, T5, and T6 vertebras showed positive correlation with heart length and width, 1 sustaining the hypothesis of using the VHS to assess increases in heart volume in black-rumped agoutis, such as what was proposed by Buchanan and Bü cheler for dogs. 3,31 High correlation was also observed in the present study between the heart and thoracic diameter, endorsing the findings reported by the same authors.…”

“…1,4,11,24 Investigation of cardiac disease by diagnostic imaging modalities is widely used in veterinary medicine. 32 However, reference values have not yet been completely established for most of the wild species, and there is little information in the literature regarding standardization of techniques to investigate cardiac disease.…”

Radiographic thoracic anatomy of the ring‐tailed lemur (Lemur catta)

“…In primates, variations in the number of thoracic vertebrae occur within a species . The number of thoracic vertebrae observed in this species (12–13) is similar to the common marmoset ( Callithrix jacchus ) .…”

“…The radiographic thoracic anatomy of the ring‐tailed lemur more closely resembles the common marmoset than other reported New and Old World monkeys . Variations exist in the normal radiographic thoracic anatomy of primates . Knowledge of the normal radiographic thoracic anatomy of individual species is important and fundamental for accurate diagnosis of diseases.…”

Descrição morfológica de duas espécies de Sapajus encontradas na Paraíba: S. libidinosus e o recém-redescoberto e já criticamente ameaçado S. flavius

“…Tal espécie já fora classificada como subespécie de S. apella (Groves et al 2005). Os S. apella são mais escuros, mais numerosos, apresentam maior distribuição geográfica entre os Sapajus, possuem diversas subespécies e extendem-se até outros países como Equador, Bolívia e Peru (Alves et al 2012, Eisenberg & Redford 1999, Groves et al 2005, Lynch Alfaro et al 2012a). …”
