“…The placing of the heart in the thoracic cavity in the middle mediastinum, with the larger portion to the left, is similar to that described for S paella, 7 T tetradactyla, 8 A paca, 9 and domestic mammals 15 and also corroborates with the results of a radiographic study with the same species as in the present study. 16 The variation in the number of ribs found has also been described in studies with another primate species, the Chlorocebus sabaeus.…”

“…The same placement and number of atrium ventricular valves has also been described for dogs and cats, S paella , and T tetradactyla . The internal structures identified in the heart of the common marmoset specimens were similar to that described for other species such as dogs and cats, P cancrivorus , and Agouti paca …”

“…In spite of the conical shape, the division of its apex by a groove differentiates it from that found in the literature for other species such as the Sapajus apella . In Tamandua tetradactyla , a conical shape is descried, but with a rounded apex.…”

“…The presence of two venae cavae, cranial and caudal, differed from that found for the Agouti paca where left cranial vena cava and right cranial vena cava were described, in addition to the caudal vena cava, but the findings for the common marmoset were in line with the description for other species, including domestic species, T tetradactyla , and Procyon cancrivorus …”

Introduction The morphological study of wild animals serves as a base for more advanced studies in clinical medicine, surgery, and pathology. Due to an urgent need and demand for professionals specialized in this area, studies of this nature have become indispensable and so the objective of the present study was to describe the heart morphology of Callithrix jacchus. Methods Ten anatomic pieces of common marmoset were used. The hearts were removed and dissected for better visualization and thus to makes a detailed description of the structures of the organ of the C jacchus species. Results The C jacchus heart is similar to that of other mammals, with small anatomical modifications such as division of the apex by the interventricular grooves, shallow fossa ovalis, and less salient intervenous tubercle. Conclusions This study may serve as taxonomic base for research and also as a basis for clinical and surgical procedures with the C jacchus.

The structure of the heart and the coronary blood supply of wild mammals, including that of threatened species, are poorly understood. This study set out to describe the heart, aortic arch branching and coronary distribution of Myrmecophaga tridactyla, and to compare it with anatomical descriptions of other Xenarthra given elsewhere. Eight adult giant anteater cadaveric specimens were used in this study. Morphological features of the heart and coronary blood supply were examined using gross dissection as well as latex and cast preparations. The heart lied in the median plane of the thoracic cavity and corresponded to a cone‐shape structure with a rounded apex facing left. The internal chambers of the heart comprised the same structures described in other mammals. Two different patterns of coronary blood supply were observed in the giant anteater. Hence, it can be concluded that the three species of Xenarthra share the same heart structure described in other mammals to date. Aortic arch branches and variations in coronary blood supply in this study have been described in carnivores, particularly the cat and the galea. The branching pattern of the coronary artery differed from that of other mammals and may be specific to Myrmecophaga tridactyla. Morphological description of the heart of the giant anteater and comparison with morphological features of other mammals, especially Xenarthra, may assist in phylogenetic analysis and provide significant contributions to clinical anatomy of practical procedures.

Radiographic pelvimetry in the Tamandua tetradactyla

et al. 2023

The pelvis, formed by the ilium, ischium and pubis, forms the coxal, which is the largest of the flat bones of the skeleton, with an important role in the physiology of birth. Vastly studied in domestic animals, there is still much to be investigated regarding the anatomical classification in wild animals, mainly aiming to improve the understanding of the reproductive management of the species. Tamandua tetradactyla is one of these species in which morphological studies are still scarce, especially when it comes to reproductive aspects. In this context, we carried out the pelvimetry of T. tetradactyla using radiographic images to anatomically and obstetrically classify the pelvis of this species, classifying it as dolicopelvic, with evidence of homoscedasticity of the samples. Verification of the existence of a relationship between the variables studied by the statistical method of Pearson coefficients showed positive correlations of high intensity for the diameters studied (P < 0.01). Thus, we believed that our findings may support future reproductive studies in this species.
