The giant anteater is one of the species classified as vulnerable to extinction. Burning and being run over are among important causes in the decrease of individuals of this species and a better knowledge of the anatomy of these animals can contribute to the treatment of injured animals and their restoration to the environment. Thus, the objective of this work was to describe aspects of the anatomy of the muscles of the forearm of M. tridactyla. For this purpose, six adult specimens were used, three females and three males. The corpses were fixed with a 10% formaldehyde solution and preserved in vats contai-ning the same solution. The thoracic limbs were dissected by routine dissection techniques. The forearm muscles of M. tridac-tyla were: brachioradialis; radial carpal extensor; common finger extensor; lateral finger extensor, ulnar carpal extensor; finger extensor I and II; long abductor of finger I; supinator, radial carpal flexor; ulnar flexor of the carpus, superficial flexor of the fingers, deep flexor of the fingers, pronator teres and square pronator, which were innervated by the radial, ulnar and median nerves. These muscles give a large volume to the forearm, are robust and have highly developed tendons, especially those invol-ved with the flexion of the carpus, digits and elbow, actions that are fundamental to your defense habits and search for food.

The aim of the present study is to describe the skin morphology and morphometry of the giant anteater (M. tridactyla), based on comparative analysis applied to skin segments from central metacarpal torus (palmar pad), dorsal thorax, ventral cervical, ventral abdomen, medial carpal and nasal regions. In order to do so, eight adult specimens of M. tridactyla were used for macroscopic studies and four for microscopic assessments. Microscopy was used to assess fur general features that were macroscopically assessed through visual analysis. Fragments (2.0cm²) were collected from the selected regions for microscopic studies. Samples were fixed on McDowell solution, processed through routine histology techniques and subjected to semi-serial cuts (5 μm). The cuts were stained in HE, Alcian blue and periodic acid Schiff. General morphology of different skin layers was described, as well as their architecture and composition; mesoscopy of the epidermis, dermis and stratum corneum was also carried out. There was difference in skin morphometry between males and females, and between different skin regions in the same animal, based on the statistical evaluation of the recorded values. All epidermis layers were assessed for the selected regions. Dermis encompassed surface and deep layers; it presented sweat and sebaceous glands, as well as hair follicles. Findings also allowed reporting that epidermis components are easily identified given its thickness, and the large amount of sweat glands in it – it contrasts its physiological features.

The Project: ''Saúde Pública em Foco'' (Public Health in Focus ) was an extension project that aimed to socialize the academic community of the Instituto Federal Goiano -Campus Urutaí and the population of the city of Urutaí -GO, through radio and social media platforms, such as Instagram, Facebook, YouTube and Podcasts. The project was based on scientific journalism for the production of programs and informative texts in simple language, seeking a better understanding of listeners and readers. We sought to provide visibility to the importance of the veterinarian for the integral health of the population, providing scientific knowledge accessible to the listener/ reader and the exchange of knowledge, through a communicational pedagogy integrated with the didactic-pedagogical practice of the teaching and learning process and dissemination of information. Public health issues, epidemiology and nonpharmacological measures to face COVID-19 were addressed. This way, the interaction with readers and listeners allowed access to information, highlighting the importance of the veterinarian in public health to face COVID-19, reducing the vulnerability of the population due to lack of access to knowledge.

This study aimed to describe the brain base arteries of the Myrmecophaga tridactyla using ten cadavers of adults from this species, including five male and five female specimens. The arterial vascular bed was perfused via the thoracic aorta with a dyed natural latex solution, and the animals were fixed and preserved with a 10% formaldehyde buffered solution. The encephala were removed, and their vessels dissected. Basilar artery formation occurred by anastomosis of the thick ventral spinal artery with vertebral arteries. The basilar artery formed two arterial islands and gave bulbar and pontine branches, and cranial, middle, and caudal cerebellar arteries and ended by forking into its terminal branches, the caudal communicating arteries. The blood supply of the encephalon derived solely from the vertebrobasilar system, and the arterial circle of the brain was closed caudally and rostrally. The absence of participation of internal carotid arteries in encephalon irrigation, the island formations by the basilar artery, and the fusiform shape of the arterial circle of the brain are peculiar characteristics of the vascular anatomy of the brain base of M. tridactyla.

As hérnias no disco intervertebral são comumente encontradas na clínica de pequenos animais, se caracterizando por extrusão ou protusão de material discal para o canal intervertebral. Assim, este relato trata-se do caso de um cão de seis anos de idade, não condrodistrófico, apresentando paresia dos membros pélvicos, quadro de disquezia, reflexo de panículo ausente a partir da quinta vértebra lombar, ausência de sensibilidade superficial e sensibilidade profunda diminuída nos membros pélvicos. Após realização de tomografia computadorizada verificousea presença de protusão e extrusão de discos intervertebrais na região lombossacral da coluna. Optou-se pela intervenção cirúrgica utilizando o método de hemilaminectomia, observando a recuperação completa do animal após sete dias.
