The purpose of this research is to describe the nasua nasua foreskin gland. Eight coatis from the CECRIMPAS Scientific Creatory (UNIFEOB) were used, the preputial glands were analyzed, dissected and described macro and microscopically, in order to establish their morphofunctional classification and thus be able to compare them with those of other species already described in the literature. Glandular tissue samples were collected, stained (hematoxylin and eosin, Toluidine blue, and picrosirius) and analyzed using light microscopy. All results were compiled and photo-documented. In the mentioned species, this gland has as its main function the territorial demarcation. In other animals such as primates, deer and rodents these demarcating glands are located in different anatomical regions, such as between the eyes, in the metatarsal, perianal and sternal. In our result of biometric measurements, we obtained an average of 3.8 ± 1.41 cm in width, 3.15 ± 0.93 cm in height and 10.26 ± 1.89 cm in circumference, and histologically classified as the tubuloalveolar type, with holocrine secretion.

The coati, is an animal with wide distribution in South America, occurring from Colombia, Venezuela to the north of Uruguay and Argentina. The general characteristics of the mamalia class are the body covered with hair (few in some) changed periodically and skin with many glands (sebaceous, sweat, odoriferous and mammary). The coati has a preputial gland, whose main function is to demarcate territory. Other animals also have demarcating glands, however, in different anatomical regions. Coatis are very territorial, and the males demarcate their territory through fights that cause serious injuries due to their cutting teeth, and secretions, among them, secretions from the preputial gland. Therefore, this work aims to study this gland, characterizing it morphologically and relating it to the reproductive behavior of males of this species. For the present study, six adult male coatis were used, provided by the scientific breeder CECRIMPAS (UNIFEOB). The preputial glands were photographed and measured, for their macroscopic characterization. As a result under macroscopic observation, the preputial glands were arranged circularly to the foreskin, forming a large increase in the region. Numerous glandular secretory ostia could be seen macroscopically when the gland was pressed to collect its secretion. The glandular secretion was stored in the gland in large quantities and had a white and viscous color.

The coati (Nasua nasua) is a long-snouted procionid, small eyes and ears, which have long canines. Their color varies according to body regions, they are omnivorous animals with diurnal, terrestrial and arboreal habits, which feed mainly on fruits and small invertebrates. For the macroscopic description of the coati respiratory system (Nasua nasua), 5 orthothanged animals were used, which were used in other research carried out at this institution, from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA as the Process: nº 02027.003731 / 04-76 . These animals were already fixed in a 10% aqueous solution of formaldehyde. The structures were identified, dissected and photo-documented. The respiratory system comprises the lungs in a system of tubes that communicate the lung parenchyma with the external environment. In the coati the nose is located in a nasal plane with a pointed shape and facing top, with its nostrils, it has the dorsal nasal concha and the ventral nasal concha, with dorsal and ventral nasal meatus.The larynx has the four cartilages the arytenoid, cricoid, epiglottis and The trachea is a cartilaginous tube that contains tracheal rings. The lungs are subdivided into lobes by deep interlobar fissures, the right lung is divided into 4 lobes and is larger than the left while the left lung has only 2 lobes. We have concluded so far that the coati respiratory system is similar to the findings described in the literature for domestic carnivores.

The objective of this work was to describe the macroscopic and microscopic morphology of the respiratory organs of the coati (Nasua nasua). Five animals from the CECRIMPAS Scientific Creatory (UNIFEOB) were used. The euthanized animals were fixed in a 10% formaldehyde solution for dissection. The respiratory devices of coatis were analyzed, measured and photo-documented. For light microscopy, fragments of the respiratory organs were collected, which were processed according to routine histology techniques and stained with hematoxylin and eosin and also Toluidine blue. In the coati the nose is located in the nasal plane, with a pointed shape and facing upwards. Internally it has the dorsal and ventral nasal concha which are separated by the dorsal and ventral nasal meatus. The larynx has four cartilages: arytenoid, cricoid, epiglottis and thyroid. The trachea contains tracheal rings separated by the tracheal ligament and is internally lined by the ciliated pseudo-stratified epithelial tissue. The lungs are subdivided into lobes by interlobar fissures, the right lung is divided into four lobes and is larger than the left, while the left lung has only two lobes. Microscopically, the primary, secondary and tertiary bronchi have the same constitution as the lining of the trachea. We conclude that the coati respiratory system is similar to the findings described in the literature for domestic carnivores.

Nasua nasua (coatis) are animals of daytime habit, widely found in Brazilian territory. These animals belong to the masked family as well as the naked hand. Its behavior is diurnal and its characteristic physical elements are the trumpet-shaped snout and the long tail used to maintain balance. For the study of the mandibular glands, 3 orthothanged animals were used, from the Scientific Creator-CECRIMPAS (IBAMA 02027.003731 / 04-76). The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. The coatis mandibular salivary glands were identified, dissected, extracted, processed and prepared for observation under an optical microscope in the hematoxylin and eosin stains, toluidine blue, picrossirius and PAS and photocumented. The coatis mandibular glands were found just below the masseter muscle and were 2.9 cm long, 1.5 cm wide and 0.8 cm thick on average. It can be concluded that, macroscopically, the mandibular salivary glands of coatis are similar in appearance and positioning to those of the other carnivores already studied. They are macroscopically multilobed and microscopically multilobulated and are constituted by mixed acini (serocomucous), a few serous acini, have striated ducts (secretors) and intercalated ducts that lead the saliva from the alveoli to the secretory ducts.

Nasua nasua (coatis) are animals of daytime habit, widely found in Brazilian territory. These animals belong to the masked family as well as the naked hand. Its behavior is diurnal and its characteristic physical elements are the trumpet-shaped snout and the long tail used to maintain balance. For this work, 3 orthothanized animals were used, coming from the Scientific Creatory (CECRIMPAS) -UNIFEOB authorized by IBAMA as the Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. The major salivary glands were identified, dissected, extracted, processed and prepared for observation under an optical microscope in the hematoxylin and eosin stains, toluidine blue, picrosirius and PAS and photocumented. Macroscopically, a pair of parotid glands can be seen located below the parotid-auricular muscle, ventral to the auricular cartilage and close to the mandibular gland. The parotid gland is attached to the auricular cartilage of coatis, measured 3.4 cm in cm in length, its width was 3.4 cm and thickness was 0.8 cm on average. This gland is multilobulated and was found to consist of serous acini, striated intralobular ducts, lined by simple prismatic epithelium, interlobular ducts that vary their epithelium from simple cubic to bi-stratified cubic and intercalated ducts lined by simple cubic epithelium.

Metatheria (Marsupialia) is a group formed by seven orders, 19 families and 81 genera, containing numerous species. It is thus organized on the basis of anatomical similarities and physiological, particularly related to reproduction. The baby carrier is located in the caudal abdominal region, has a horseshoe shape and inside the mammary papillae are "U", in number of 11, arranged in pairs except one that was centrally located, and the papillae that were connected to the pups were more developed, in relation to the length, and the rest had an inactive aspect. The respiratory system comprises the lungs and a system of tubes that communicate the lung parenchyma with the outside environment. It is customary to distinguish in the respiratory system, a conductive portion formed by the nasal fossae, nasopharynx, larynx, trachea, bronchi and bronchioles, and a respiratory portion represented by the terminal portions of the bronchial tree and containing the alveoli, the only place where exchanges take place. gaseous. Between these two there is a short portion, called a transition. The research aimed to describe the macroscopic morphology of the trachea and larynx of opossums (Didelphis sp.). Five opossums, euthanized, from the Unesp breeding farm in Araçatuba were used. The possums' trachea and larynx were measured using a caliper and the larynx cartilages were separated and also measured according to the following parameters: a) weight; b) latero-lateral width; c) cranio-caudal height; d) dorsoventral length. The trachea and larynx of the respective animals were photographed using a Sony Mavica 3.2 MP digital camera. The nomenclature used was referred to according to the International Commitee on Veterinary Gross Anatomical Nomenclature (2005).

The coati (Nasua nasua) is a carnivore belonging to the Procyonidae family that inhabits the entire South American continent. Due to the lack of studies related to anatomical-surgical segmentation and the morphology of the bronchial tree, the objective of this work was to characterize the bronchial tree macro and microscopically for future comparisons in other studies with wild animals. For this work, four euthanized animals (coatis) were used, from CECRIMPAS / UNIFEOB- IBAMA 02027.003731 / 04-76. The bronchiopulmonary segments were identified according to their position pattern in relation to the pulmonary lobe, and the microscopic analysis of the bronchial tree was performed using a routine H.E (hematoxylin / eosin) staining technique. In the lungs of the coatis, 24 bronchiopulmonary segments were found: four in the left cranial lobe; five in the left caudal lobe; three in the right cranial lobe; three in the right middle lobe; four in the right accessory lobe and five in the right caudal lobe. It was found in this work that the lobation of the lungs of coatis are similar to that of domestic carnivores and that microscopically the bronchial tree of coatis is similar to that of the other mammals described in the literature consulted, with great variations in its architecture according to the bronchial tree. branches, decreasing in diameter and thickness of its walls.
