“…The number of ribs (including floating ribs), vertebrae (including the anticlinal vertebra) and sternebrae were recorded. The length and height of the vertebrae and sternebrae were measured on the RL projection from the midpoint of the cranial end plate to the caudal end plate (length) ( Fig 1 ) and along the cranial endplates (height) [ 24 ].…”

“…The tracheal diameter and more precisely the trachea to thoracic inlet ratio was calculated as proposed in dogs and monkeys [ 24 , 36 ]. The tracheal inclination was calculated as the angle formed by the ventral surface of the bodies of the thoracic vertebrae and the trachea [ 30 ].…”

“…Thoracic radiography is essential to access lower airway disease and is commonly used in non-human primates. The radiographic thoracic anatomy has been studied in many other more or less similar species like ring-tailed lemur ( Lemur catta ) [ 24 ], Goeldi’s monkey ( Callimico goeldi ) [ 25 ], Rhesus macaque [ 26 ], Cynomolgus monkey ( Macaca fascicularis ) [ 27 ], pet macaques of Sulawesi (Macaca nigra and tonkeana )[ 28 ], vervet monkey ( chlorocebus sabaeus ) [ 29 ] and also in close species as in capuchin ( Cebus paella ) [ 30 ]. The tracheal morphology has also been studied in Saimiri spp.…”

The purpose of this prospective study was to describe the normal anatomy and provide reference ranges for measurements of thoracic radiography on Squirrel monkeys (n = 13). Thoracic radiography is a common non-invasive diagnostic tool for both cardiac and non-cardiac thoracic structures. Furthermore cardiac disease is a common condition in captive primates. In this study, left-right lateral, right-left lateral and dorsoventral projections of 13 healthy Squirrel monkeys were reviewed during their annual health examinations. The mean Vertebral Heart Score on the left-right and right-left lateral projections were 8,98 ± 0,25 and 8,85 ± 0,35 respectively. The cardio-thoracic ratio on the dorsoventral projection was 0,68 ± 0,03. The trachea to inlet ratio was 0,33 ± 0,04. Other measurements are provided for the skeletal, cardiac and respiratory systems. Knowledge of the normal radiographic thoracic anatomy is fundamental in clinical as well as research settings for accurate diagnosis of diseases.

“…Os hemipumões foram divididos em lobações, o lado direito possuiu lobos cranial, médio, caudal e acessório; o lado esquerdo possuiu parte cranial e caudal do lodo cranial e lobo caudal, a semelhança de lêmures (Makungu et al 2014) e sauim (Chagas et al 2012). O hemipulmão direito era maior; ambos apresentaram uma base (superfície diafragmática), um ápice, duas extremidades (costal e medial) e três bordas (dorsal, ventral e basal) (Fig.1F) como a maioria das espécies (König & Liebich 2004).…”

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

et al. 2016

RESUMO.-Sapajus flavius e S. libidinosus são duas espécies de macacos-prego encontrados no Estado da Paraíba. S. flavius ou macaco-prego-galego foi recentemente redescoberto e está criticamente ameaçado de extinção, sendo encontrado em fragmentos remanescentes de mata Atlântica do litoral do RN, PB, PE e AL. S. libidinosus tem uma distribuição e população maior, coexistindo de S. flavius na PB, entretanto, ocupando o oeste da PB, na caatinga. Frente à lacuna no conhecimento sobre estas espécies foi realizada a descrição morfológica das mesmas, envolvendo biometria externa, dos órgãos do trato gastrointestinal, topografia visceral e a descrição anatômica. Apesar da literatura descrever S. flavius como o menor dos Sapajus, concluímos que não há diferenças morfológicas entre as espécies estudadas. Tais informações servem de subsídios para melhores manejos visando a conservação das espécies e ajudando na classificação taxonômica desse gênero recentemente modificado. INTRODUÇÃOO macaco-prego-dourado ou macaco-prego-galego (Sapajus flavius) é uma espécie de macaco-prego que há muito se acreditava estar extinta, sendo redescoberta recentemente (Pontes et al. 2006 rromaoguerra@gmail.com Sapajus flavius and S. libidinosus are two species of capuchin monkeys found in the state of Paraíba, Brazil. S. flavius or Macgrave´s capuchin monkey was recently rediscovered and is now critically endangered, found only in remaining fragments of Atlantic forest in the coastal region of the Brazian Northeast. S. libidinosus has a larger population and distribution, coexisting with S. flavius in Paraíba, however living in the western part of the state, in the semi-arid. Since there is a lack of knowledge about these species, a morphologic description of them was made, involving external and gastrointestinal tract biometry, visceral topography and anatomic description. Although the literature describes S. flavius as the smaller monkey of the Sapajus genus, we conclude that there are no morphological differences between these species. Such information contributes to best management practices for conservation of the species and to the correct taxonomic classification of the genus recently modified.

“…Contrary to the Sapajus sp., in the Alouatta guariba the anatomical presentation of the heart in the thoracic cavity occupies only the left hemithorax, similar to the Lemur catta (16) . It is different from that of the Chlorocebus sabaeus species in which the cardiac base is situated in the right hemithorax (17) , a factor that precludes the relation of the CTR derived post ventrodorsal radiography, as performed for the genus Sapajus sp.…”

Heart Measurements of Non-Human Primates by Radiographic Techniques

et al. 2019

Thoracic Radiology is a diagnostic technique used to study several aberrations, including cardiac abnormalities, which can be determined by VHS (vertebral heart size). The heart length and width are measured, and the CTR (cardiothoracic ratio) is calculated, by comparing the heart width to the thoracic diameter. This study aimed at measuring the cardiac silhouette of non-human primates (PNH) belonging to the genus Sapajus sp., and the Alouatta guariba species through VHS and CTR. From among the eight animals assessed, it was evident that in both the Sapajus sp. and the Alouatta guariba, the highest HSV change index was observed, depending upon the age of the animal. However, although the individuals of the Alouatta guariba species are bigger in size and heavier, the animals of the genus Sapajus sp. have a larger heart size in proportion to their body. ResumoO uso da radiologia torácica surge como forma de diagnóstico para inúmeras anormalidades, inclusive cardíacas, as quais podem ser avaliadas por métodos VHS (vertebral heart size), realizado a partir da mensuração do comprimento e largura do coração e CTR (cardiothoracic ratio), o qual compara a largura do coração, pelo diâmetro torácico. Assim, objetivamos mensurar a silhueta cardíaca de primatas não humanos (PNH) do gênero Sapajus sp. e espécie Alouatta guariba por meio do VHS e CTR. Dos oito animais avaliados, percebeu-se que tanto nos Sapajus sp. e nos Alouatta guariba, o índice de maior alteração do VHS foi encontrado pela idade do animal. E que apesar dos animais da espécie Alouatta guariba serem maiores e mais pesados, proporcionalmente ao corpo, os animais do gênero Sapajus
