Nine-banded armadillo (Dasypus novemcinctus) stands out for its adaptability in different environments, a fact that requires the species, an olfactory capacity developed with a keen sense and related organs potentially evolved. Five specimens of nine banded armadillo were submitted to anatomic dissection with occipital disconnection and isolation of part of the skull in order to obtain a hemi-skull to view the arrangement of internal structures of the nasal cavity. The obtained specimens were identified and photographed with the assist of digital camera. The nine-banded armadillo nose is incorporated into the face of the skeleton located in nasal plan with the triangular shape and facing forward. The nostrils are separated by the nasal septum. Paranasal sinuses, two (frontal and parietal), resemble diverticula of the nasal cavity. The nine-banded armadillo nasal shells are presented divided into three: the ethmoid shell, the dorsal nasal shell and the ventral nasal shell. The shells are delimited dorsal and ventral nasal meatus by. The respiratory system of nine-banded armadillo presented features anatomical that justify their behavior in the nature, as their olfactory ability for hunting. Thus, the development of the nasal shell, especially, ethmoid shells check the animal facility in the searching for subterranean food https://doi.galoa.com.br/doi/10.17648/jibi-2448-0002-1-1-4013

This article reviews current surgical techniques for a deviated septum and, in particular, focuses on the comparison of conventional and endoscopic approaches to septoplasty. Relevant issues of the anatomy and physiology of the nasal septum affecting the course of the comorbidities of the nasal cavity and the surrounding structures are discussed. The conventional and endoscopic approaches to septoplasty, indications, the benefits and drawbacks of each technique are addressed. The authors highlight the spectrum of the potential surgical procedures to the surrounding structures with the correction of the deviated septum as the first step. This surgical strategy in patients with the combined disorders of the internal structures of the nasal cavity is accounted for by the favorable course of the chronic conditions of the nasal cavity in the postoperative period and the possibility for providing adequate care for the nasal cavity. This article describes authors’ experience with the surgical correction of the deviated septum using endoscopic approach at all steps of the surgery. Clear advantages of this techniques in terms of both intraoperative accuracy and postoperative care for the nasal cavity are uncovered.

The study analyzed the functional parameters of nasal breathing, linear parameters of the nasal aperture, nasal cavity and nasopharynx, volumetric parameters of the upper airways in patients with II and III skeletal class of jaw anomalies before and after orthognathic surgery. The respiratory function of the nose was assessed using a rhinomanometric complex. According to rhinoresistometry data, nasal resistance and hydraulic diameter were assessed. According to the data of acoustic rhinometry, the minimum cross-sectional area along the internal valve, the minimum cross-sectional area on the head of the inferior turbinate and nasal septum and related parameters were estimated. According to the CBCT data, the state of the nasal septum, the inferior turbinates, the nasal aperture, the state of the nasal cavity, and the linear values of the upper respiratory tract (nasopharynx) were analyzed. The patients were divided into 4 groups according to the classification of the patency of the nasal passages by

Abstract Traversodontidae is a group of Triassic herbivorous/omnivorous cynodonts that represents the most diversified lineage within Cynognathia. In southern Brazil, a rich fossil record of late Middle/mid-Late Triassic cynodonts has been documented, with Exaeretodon riograndensis Abdala, Barberena, and Dornelles, 2002 and Siriusgnathus niemeyerorum Pavanatto et al., 2018 representing two abundant and well-documented traversodontids. The present study provides a comparative analysis of the morphology of the nasal cavity, nasal recesses, nasolacrimal duct, and maxillary canals of both species using computed tomography, highlighting the changes that occurred in parallel to the origin of mammaliaforms. Our results show that there were no ossified turbinals or a cribriform plate delimiting the posterior end of the nasal cavity, suggesting these structures were probably cartilaginous as in nonmammaliaform cynodonts. Both species show lateral ridges on the internal surface of the roof of the nasal cavity, but the median ridge for the attachment of a nasal septum is absent. Exaeretodon riograndensis and S. niemeyerorum show recesses on the dorsal region of the nasal cavity, which increase the volume of the nasal cavity, potentially enhancing the olfactory chamber and contributing to the sense of smell. On the lateral sides of the nasal cavity, the analyzed taxa show a well-developed maxillary recess. Although E. riograndensis and S. niemeyerorum have roughly similar nasal cavities, in the former taxon, the space between the left and right dorsal recesses of the nasal cavity is uniform along its entire extension, whereas this space narrows posteriorly in S. niemeyerorum. Finally, the nasolacrimal duct of S. niemeyerorum is more inclined anteroposteriorly than in E. riograndensis.

Extracranial meningiomas may be subdivided into primary and secondary types based on absence or presence of intracranial attachments respectively. Primary sinonasal tract meningiomas are rare with unknown etiopathology and non-specific clinical presentation. Of these PEMs only 11.5% are in the nasal cavity and nasal septum. To our knowledge less than 50 cases of PEM of nasal cavity have been reported in the literature. We report a case of a 22 years old male who presented with epistaxis and increasing nasal stuffiness for the last one year.

Recently, among other processes in modern architecture, a lot more attention is expressed towards the fourth dimension (4D). This process is caused as an opposition to pragmatic functionalism, utilitarity, unification, formal deconstructyvism, sophistication. The expression of 4D in contemporary architecture is an intention to change the face of modern architecture, giving it more expressiveness, modern innovation. It results in specific aims and priorities of architectural expression. Architecture of today contains a variety of artistic areas (video, installation, painting, sculpture, graphics) as integral parts of its surface or internal structures. A building becomes an object of interdisciplinary art. The integration of interactive hypersurfaces in exteriors and interiors leads to various aspects of 4D in modern architecture. The paper discusses various aspects of 4D in architecture, excluding several marginal cases showing a wide range of aspects and priorities. Santrauka Pastaruoju metu, šalia kitų reiškinių, šiuolaikinėje architektūroje vis aktyviau reiškiasi ketvirtosios dimensijos vaidmuo. Šį procesą lemia priešprieša pragmatiškam funkcionalizmui, utilitarumui, unifikacijai, formaliam dekonstrukciniam laužymui, įmantrumui, daugžodžiavimui. 4D raišką šiuolaikinėje architektūroje formuoja siekis keisti architektūros „veidą“, suteikiant jai daugiau išraiškingumo, įtaigumo ir šiuolaikinio novatoriškumo. Tai lemia specifinius architektūrinės raiškos tikslus ir prioritetus. Šiuolaikinė architektūra įtraukia į save įvairių meno krypčių (videomenas, instaliacija, tapyba, skulptūra, grafika) elementus ne kaip atskirus meno objektus, o kaip neatsiejamus pastato paviršiaus ar vidaus struktūrinius darinius. Pastatas tampa tarpdisciplininiu meno objektu. Interaktyvių hiperpaviršių integravimasis eksterjere ir interjere lemia įvairius ketvirtosios dimensijos aspektus šiuolaikinėje architektūroje, kurie ir yra nagrinėjami šiame straipsnyje. Straipsnyje aptariami įvairūs ketvirtosios dimensijos šiuolaikinėje architektūroje aspektai ir sritys, išskiriami kraštutiniai, charakteringi atvejai, atspindintys platų tikslų ir prioritetų diapazoną. Aptariami, autorių manymu, charakteringiausi šios raiškos atvejai, daugiausiai dėmesio skiriant hiperpaviršių įtakai ketvirtosios dimensijos pasireiškimui šiuolaikinėje architektūroje.

The nasal cavity is the entrance to the respiratory tract. Its functions are to clean, warm, and humidify air as it is inhaled. Respiratory mucosa covered by pseudostratified ciliated epithelium and goblet cells, as described in Chapter 5 and illustrated in Figure 5.2B, lines the majority of the nasal cavity. The cilia and mucus trap particles, thus cleaning the air; the mucus also humidifies the air and warming is achieved through heat exchange from blood in the very vascular mucosa. The efficiency of all these processes is increased by expanding the surface of the nasal cavity by folds of bone. The nasal cavity also houses the olfactory mucosa for the special sense of olfaction although the olfactory mucosa occupies a very small proportion of the surface of the nasal cavity. The nasal cavity extends from the nostrils on the lower aspect of the external nose to the two posterior nasal apertures between the medial pterygoid plates where it is in continuation with the nasopharynx. Bear in mind that in dried or model skulls, the nasal cavity is smaller from front to back and the anterior nasal apertures seem extremely large because the cartilaginous skeleton of the external nose is lost during preparation of dried skulls. As you can see in Figure 27.1 , the nasal cavity extends vertically from the cribriform plate of the ethmoid at about the level of the orbital roof above to the palate, separating it from the oral cavity below. Figure 27.1 also shows that the nasal cavity is relatively narrow from side to side, especially in its upper part between the two orbits and widens where it sits between the right and left sides of the upper jaw below the orbits. The nasal cavity is completely divided into right and left compartments by the nasal septum . From the anterior view seen in Figure 27.1 , you can see that the surface area of lateral walls of the nasal cavity are extended by the three folds of bone, the nasal conchae. The skeleton of the external nose shown in Figure 27.2 comprises the nasal bones, the upper and lower nasal cartilages, the septal cartilage, and the cartilaginous part of the nasal septum.

Respiratory epithelial adenomatoid hamartoma (REAH) is a rare lesion in nasal cavity first reported by Wenig and Heffner in 1995. Most commonly seen in men in third to ninth decade of life. Majority of cases presents as a polypoidal mass in one or both nasal cavities. We experienced such a case of REAH originating from the nasal septum, in posterior aspect, treated by endoscopic approach. It is important to differentiate REAH from other sinonasal pathologies like inverted papilloma and low grade sinonasal adenocarcinoma. Complete surgical resection is the treatment of choice.

International labor migration has been a major feature of the Philippine political economy the past twenty years. Originally envisioned by the government as a temporary measure to ease domestic employment pressure and stimulate industrialization, migration has persisted in the face of declining wages and abusive recruitment practices. Dynamic movement patterns have emerged that include a variety of destinations and occupations, drawing both males and females from widely diverse backgrounds. Focusing upon the experiences of a small community, this study suggests that contract labor is best understood within the migration process, linking global economic formations and domestic policy to internal structures in sending communities. The community experience reveals that economic forces and government policy are necessary conditions to establish potential migration, but actual flows are initiated and shaped by a migration system consisting of interpersonal relationships. What becomes more visible at the community level are the distinct phases of overseas employment, or periods of time dominated by particular types of migration and varying potential to achieve economic gains from such. The emergence and evolution of networks are analyzed for their role in shaping patterns of labor migration.
