(2018) Miranda, Maria Eduarda Luiz Coêlho de; Amorim, Marleyne José Afonso Accioly Lins; http://lattes.cnpq.br/1237734889563996; http://lattes.cnpq.br/6485172910664692
Bradypus variegatus is a species of the family Bradypodidae and superorder Xenarthra, with a peculiar life habit and does not largely occur in quantity around the world as Brazil. It should be considered as a multidisciplinary biological model, making possible the maintenance of several biological studies. Particularly emphasizing the importance of morphological research, since these animals present great anatomical variation, mainly in the arterial vascularization. Thus, an anatomical description of sloth B. variegatus was performed from the external carotid artery (a.) and its branches. The corpses were acquired through the Wild Screening Center CETAS/IBAMA. Procedures were authorized by Animal Use and Experimentation Ethic Committee CEUA/UFRPE license nº 034/2015. Ten adult animals, all females, were sampled and submitted to dissection, then it was verified that the common carotid a. bifurcates over the external and internal carotid at the level of first tracheal ring. The external carotid extends to the maxilla, where creates branches to the temporal region and eye posterior pole. For all sampled animals, seven principal branches of external carotid were observed, and according to their origin and location were denominated as auricular, lingual, facial, bottom alveolar, temporal, maxillary and ophthalmic arteries. The maxillary and ophthalmic branches correspond to the terminals and others are lateral branches. In 50% of the animals sampled, the presence of arterial anastomoses was verified and 40% of them presented the addition of a branch to the principal. Almost one third (30%) of these demonstrated the presence of a tracheal branch and 10% of a sublingual branch, being these lateral branches. This study corroborates the understanding about the head and neck vascularization of sloth, aiding in the medical clinic of these animals.
Descrição do plexo braquial do bicho-preguiça Bradypus variegatus Schinz, 1825 (Mammalia: Pilosa)

The species of Bradypus variegatus is known as common sloth. It is an endemic mammal of Neotropical regions, which suffers from devastating human action. These Bradipodids were submitted to the three thoracic and pelvic, consecrated arboreal and descend to the ground only to excrete and change trees. The study had as its origin the brachial plexus of B. variegatus in relation to the origin and distribution of the nerves. For this, 10 adult females were used. A sós were carried out in the Anatomy Pavilion of the Department of Morphology and Physiology of the Animals of the Federal Rural University of Pernambuco, under license nº 034/2015 of the Ethics Committee on the Use of Animals. The corpses were preserved after natural death, fixed at 20%, preserved in 30% solution in tanks and dissected to visualize the nerves destined to innervate the limbs and thoracic muscles. Once done, which is the brachial plexus of the common laziness originates from the fifth cervical segment, and is tracing to the second thoracic segment. It is formed by the long and suprascapular thoracic nerves, of immediate origin of the medial segment 5 and 6, and by the pectoral, subscapular, axillary, radial, musculocutaneous, medial, medial cutaneous nerves of the forearm and ulnar, with the effect of a trunk formed from of cervical spinal nerves (C) 7, C8, C9, and thoracic (T) 1 and T2. Compared with other animals, the wild rays and rays of light relative to the origin of the B. variegatus plexus, however, the constituent nerves and their innervation areas were not discrepancies.
Estudo anatômico do cerebelo de Bradypus variegatus, Schinz 1825 (Mammalia: Pilosa)
(2022-05-24) Oliveira, Ueliton da Silva; Amorim, Marleyne José Afonso Accioly Lins; http://lattes.cnpq.br/1237734889563996; http://lattes.cnpq.br/9250603868698523
The common sloth (Bradypus variegatus, Schinz 1825) is an arboreal quadruped species belonging to the Class Mammalia, Superorder Xenarthra and Family Bradypodidae. In South America, it inhabits from northern Colombia to southwestern Venezuela, southern Ecuador, eastern Peru and Bolivia, in addition to being present in Brazil. In the case of organic systems, bradypodids have certain anatomical peculiarities such as double posterior vena cava, six to nine cervical vertebrae depending on the species; common duct for the urinary and genital tracts in females and internal testes in males. However, there are few studies concerning the central nervous system, especially when comparing them to domestic animals. Therefore, the present work aims to analyze, describe and morphologically characterize the cerebellar structures of the Bradypus variegatus sloth. 10 animals were used for the analyses, obtained after natural death from the Wild Animal Screening Center, and fixed in 20% formaldehyde. Reserved in numbered tanks in 30% saline solution, the animals also received individual identifications. The skullcap and brain were removed to gain access to the cerebellum. The organ was separated from the brain stem by a cross section and preserved in a 20% formaldehyde solution in glass reservoirs. The cerebellar structure of common sloths, in both males and females, was, on average, 1.21 cm long by 1.62 cm wide. From the analysis carried out, it is concluded that the B. variegatus cerebellum has an ovoid morphology, slightly flattened in the cranial and caudal lateral portions, presenting the worm in the central region, right and left hemispheres with lobes and fissures, which corroborate with descriptive studies performed on humans and domestic animals.
Identificação dos ramos tributários da veia porta hepáticana preguiça-comum, Bradypus variegatus Schinz, 1825 (Pilosa:Bradypodidae)

Bradypus variegatus,commonly known as common sloth, is a species belonging to the Bradypodidae family. The sloths are considered a biological model and can be applied to multidisciplinary research, since the animals present morphological differences and share the uncommon characteristic when compared with other eutherians. Thus, this study was developed to be applied the medical clinic and the proper management of sloths, aiming to approach the anatomical aspects of the mammal, especially whendealing with the cardiovascular system. Ten sloths were used obtained after natural death, through the CETAS/CPRHWildlife Screening Center, the collection belongs of area anatomy of the Department of Morphology and Animal Physiology of the FederalRural University of Pernambuco, where the research was also carried out. The animals were fixed in 20% aqueous solution of formaldehyde and then advanced in a 30%saline tank. For an assembly of the results the specimens were submitted to dissection technique. In 80% of the observations the portal vein originated from five tributaries, namely: the mesenteric trunk, the vein formed by anastomoses of the cardic vein, fundicveinand pyloric branches, the vein resulting fron the union of branches of the stomach body with branches of the cranial portion of the cardic cavity, pyloric vein and splenic vein. In 20% of the animals, theportal vein consists of six tributaries, since the fundic vein and the cardic vein perform two direct anastomoses with a tranverse disposition, arriving the hepatic portal vein two tributary vessels. It was found, therefore, that the hepatic portal systemis responsible for the drainage of the stomach, spleen, pancreas and intestines, as in most mammals;
