Introduction: The pterygopalatine fossa (PPF) is a narrow space located between the posterior wall of the antrum and the pterygoid plates. Surgical access to the PPF is difficult because of its protected position and its complex neurovascular anatomy. Endonasal approaches using rod lens endoscopes, however, provide better visualization of this area and are associated with less morbidity than external approaches. Our aim was to develop a simple anatomical model using cadaveric specimens injected with intravascular colored silicone to demonstrate the endoscopic anatomy of the PPF. This model could be used for surgical instruction of the transpterygoid approach. Methods: We dissected six PPF in three cadaveric specimens prepared with intravascular injection of colored material using two different injection techniques. An endoscopic endonasal approach, including a wide nasoantral window and removal of the posterior antrum wall, provided access to the PPF. Results: We produced our best anatomical model injecting colored silicone via the common carotid artery. We found that, using an endoscopic approach, a retrograde dissection of the sphenopalatine artery helped to identify the internal maxillary artery (IMA) and its branches. Neural structures were identified deeper to the vascular elements. Notable anatomical landmarks for the endoscopic surgeon are the vidian nerve and its canal that leads to the petrous portion of the internal carotid artery (ICA)...

Described in this article is a novel device that facilitates study of the cross-sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling during anatomy laboratory while also ensuring excellent visualization of the anatomic structures. We used an electric saw to create 15-mm sections of three cadaver heads in the three traditional anatomic planes and inserted each section into a thin, perforated display box made of transparent acrylic material. The thin display boxes with head sections are kept in anatomical order in a larger transparent acrylic storage box containing formaldehyde solution, which preserves the specimens but also permits direct observation of the structures and their anatomic relationships to each other. This box-within-box design allows students to easily view sections of a head in its anatomical position as well as to examine internal structures by manipulating individual display boxes without altering the integrity of the preparations. This methodology for demonstrating cross-section anatomy allows efficient use of cadaveric material and technician time while also giving learners the best possible handling and visualization of complex anatomic structures. Our approach to teaching cross-sectional anatomy of the head can be applied to any part of human body...

Paepalanthus sect. Diphyomene has inflorescences arranged in umbels. The underlying bauplan seems however to be more complex and composed of several distinct subunits. Despite appearing superficially very similar, the morphology and anatomy of the inflorescences can supply useful information for the understanding of the phylogeny and taxonomy of the group. Inflorescences of Paepalanthus erectifolius, Paepalanthus flaccidus, Paepalanthus giganteus, and Paepalanthus polycladus were analyzed in regard to branching pattern and anatomy. In P. erectifolius, P. giganteus and P. polycladus the structure is a tribotryum, with terminal dibotryum, and with pherophylls bearing lateral dibotrya. In P. flaccidus, the inflorescence is a pleiobotryum, with terminal subunit, and without pherophylls. Secondary inflorescences may occur in all species without regular pattern. Especially when grown in sites without a pronounced seasonality, the distinction between enrichment zone (part of the same inflorescence) and new inflorescences may be obscured. The main anatomical features supplying diagnostic and phylogenetic information are as follows: (a) in the elongated axis, the thickness of the epidermal cell walls and the cortex size; (b) in the bracts, the quantity of parenchyma cells (c) in the scapes...

Com a rápida evolução da odontologia veterinária na última década, faz-se crescente a busca pelo conhecimento da área e a busca por referências bibliográficas, porém nota-se que as informações existentes de uma área essencial, a anatomia, estão limitadas a descrições básicas. Sabe-se que o conhecimento da anatomia do sistema estomatognático é de fundamental importância para que clínicos e cirurgiões possam diagnosticar e instituir tratamento adequado e preciso. Apesar dos livros de odontologia veterinária apresentarem descrições das mais simples até as mais complexas intervenções cirúrgicas, nenhum descreve detalhadamente a morfologia dentária e ainda menos suas correlações com as técnicas cirúrgicas e disfunções do sistema estomatognático o que facilitaria e daria maior precisão ao ato cirúrgico. Contudo, tais informações existem em abundância na literatura odontológica humana; considerando-se ainda, que já se faz nos animais grande parte dos procedimentos feitos no ser humano, conclui-se a importância de obter essas informações também para a prática da odontologia veterinária. Propõe-se estudar cada elemento dental individualmente, correlacionando-os com suas principais afecções. Além disso...

Este trabalho apresenta o levantamento anatômico da madeira de 107 espécies distribuídas em 11 gêneros pertencentes à família Sapotaceae (ordem Ericales), do continente americano, dentre os quais Manilkara Adanson, Sideroxylon Linnaeus, Micropholis (Grisebach) Pierre, Chromolucuma Ducke, Sarcaulus Radkolfer, Elaeoluma Baillon, Pouteria Aublet, Chrysophyllum Linnaeus, Ecclinusa Martius, Pradosia Liais e Diploon Cronquist. Na mais recente tentativa de classificação, Pennington (1990, 1991) reconheceu cinco tribos com base, principalmente, em características da flor e da semente. De acordo com o próprio pesquisador, quatro das tribos representariam grupos naturais, provavelmente monofiléticos. Entretanto Swenson & Anderberg (2005), utilizando a análise molecular combinada com características morfológicas, concluíram que os dois maiores gêneros da família, Chrysophyllum e Pouteria são polifiléticos. Desse modo, a família Sapotaceae necessita de uma revisão e inúmeros autores (Record, 1939; Kukachka, 1978a) mencionaram a necessidade de mais informações anatômicas do xilema para complementar e ampliar os estudos taxonômicos e filogenéticos. Portanto, este trabalho tem como objetivo verificar se a anatomia da madeira corrobora a classificação proposta por Pennington em 1990 e a obtenção de informações que possibilitem indicar características anatômicas de valor diagnóstico e estatístico...

Os estudos da anatomia macro e microscópica do lenho como ferramenta auxiliar na taxonômia, sobretudo na identificação de espécies florestais, vêm sendo utilizados há décadas. A análise comparativa da estrutura anatômica do lenho permite a identificação de características morfológicas exclusivas das ordens, famílias, gêneros e, em muitos casos, de espécies, aumentando a gama de caracteres utilizados na descrição e identificação botânica de espécies arbóreas pela taxonomia clássica. No presente trabalho, foram utilizadas técnicas de análise comparativa e de descrição da estrutura anatômica macro e microscópica do lenho de árvores de espécies que ocorrem naturalmente na floresta tropical Amazônica nos municípios de Santarém, Mojú, Paragominas e Tailândia, no estado do Pará. Os objetivos do trabalho foram (i) caracterizar a estrutura anatômica macro e microscópica do lenho; (ii) identificar as características de valor taxonômico através de análise comparativa da estrutura anatômica do lenho; (iii) elaborar chaves de identificação das espécies pela estrutura anatômica macro e microscópica do lenho. Foram analisadas 100 amostras do lenho do tronco de árvores de 64 espécies, coletadas em 2004...

INTRODUÇÃO: Estudos experimentais e clínicos, realizados por diversos autores, demonstraram a susceptibilidade à compressão nervosa periférica na vigência da diabetes mellitus e modificações na evolução natural da doença após descompressões nervosas cirúrgicas dos sítios propícios a constrição neural. Em membros inferiores, a síndrome do túnel do tarso sobreposta às neuropatias vigentes ainda gera conflitos na literatura. A anatomia do nervo tibial e seus ramos ao nível do terço distal da perna e túnel do tarso apresentam variações importantes que não são contempladas nos livros texto e atlas de anatomia. OBJETIVO: Determinar, através de dissecção em cadáveres frescos, a anatomia topográfica do nervo tibial e seus ramos ao nível do tornozelo, em relação ao túnel do tarso. MATERIAL E MÉTODOS: O estudo foi realizado através da dissecção anatômica bilateral de 26 cadáveres frescos. Foi fixada, entre o cento do maléolo medial e o centro do calcâneo, uma linha de referência (eixo maleolar-calcaneal). Com base nesse eixo as localizações da bifurcação do nervo tibial e dos ramos calcâneos mediais e inferiores foram aferidas em milímetros. Para as bifurcações foi estabelecida uma classificação por tipos de I a V...

Several leaf anatomical features are potentially systematically informative within both the family Vochysiaceae and the order Myrtales, notably tracheoidal idioblasts, mucilage cells and secretory canals. Tracheoids with spiral wall thickenings are present in the mesophyll of most species of Vochysia, and also occur in several other families of Myrtales. Mucilage cells are common in the leaf epidermis in some Vochysiaceae. Secretory ducts are present in the midrib in Salvertia and Vochysia, which are apparently closely related, although Salvertia also shares some leaf anatomical characters with Qualea and Callisthene. Anatomical data do not support the segregation of Ruizterania from Qualea; leaves of R. albiflora leaves are very similar to those of Q. paraensis in venation pattern, and leaf and stem anatomy. Different venation patterns are characteristic of sections within the genus Qualea, but within the large genus Vochysia, leaf anatomy is variable even within a subsection. Amongst other Myrtales, leaf anatomy of Vochysiaceae most closely resembles that of Combretaceae and Onagraceae. © 2002 The Linnean Society of London.

Leaves of Artemisia annua L. are a plentiful source of artemisinin, a drug with proven effectiveness against malaria. The aim of this study was to classify the photosynthetic mechanism of A. annua through studies of the carbon isotope composition (δ 13C) and the leaf anatomy. A. annua presented a δ 13C value of - 31.76 ± 0.07, which characterizes the plants as a typical species of the C3 photosynthethic mechanism, considering that the average δ 13C values for C3 and C4 species are -28 and -14, respectively. The leaf anatomy studies were consistent with the δ 13C results, where, in spite of the existence of parenchymatic cells forming a sheath surrounding the vascular tissue, the cells do not contain chloroplasts or starch. This characteristic is clearly different from that of the Kranz anatomy found in C4 species.

Floral nectaries have contributed to the systematics of different taxonomic groups. Since those of the neotropical genera included in subfamily Salacioideae-Cheiloclinium Miers, Peritassa Miers, Salacia L. and Tontelea Aubl.-have different forms and positions, we explored their anatomy to delimit more precisely the genera of subfamily Salacioideae. Buds and open flowers of six species were treated following the usual techniques in plant anatomy. The obtained data were helpful in characterizing the floral nectary anatomy of the studied species. Furthermore, some features such as form, position and surface of nectaries; form of their epidermal cells; presence and distribution of stomata; occurrence of idioblasts containing druses in the nectariferous parenchyma; and absence of nectary vascularization can contribute to the taxonomy and phylogeny of the Salacioideae studied. In most of the studied species the nectar is probably released by both the stomata and the nectary epidermal surface. In Cheiloclinium cognatum, the structure acknowledged as nectary is actually a vestigial tissue and the functions of attracting and rewarding pollinators has phylogenetically migrated to the stigmatic region. The druses and phenolic substances observed in the nectariferous parenchyma probably help defend flowers against herbivore attacks. The minute size of the nectaries of Salacioideae may explain the absence of vascularization. The floral nectaries of Salacia elliptica are epithelial while those of the other species are mesenchymal. © 2012 Springer-Verlag Wien.

Non-human primates have constituted an important group among animals subjected to various studies. Ethological, evolutionary and paleontological studies have revealed changes in anatomical structures linked to the evolution of primates, considered in studies on the comparative anatomy between Cebus libidinosus and other neotropical monkeys or those from the Old World, and the detailed knowledge on their anatomy may represent an important factor for their preservation and protection when the animals are brought to veterinary clinics after accidents or illnesses. In terms of veterinary importance, sometimes these animals arrive in the veterinary medical clinics after accidents, needing surgery or clinical treatment, but the little data available on anatomy has impaired the correct proceedings. The main justification for studies on C. libidinosus, is due to little information about the anatomy related to C. libidinosus in Brazilian and worldwide scientific literature. In this study, the distribution, enervation and path of the femoral and sciatic nerves of the pelvic limb (thigh) of C. libidinosus were studied and these results were compared with literature on the anatomy of humans, chimpanzees and baboons. In general, the enervation model of the four primates is identical...

The objective of this work was to evaluate the effects of the population density of Typha angustifolia plants in the anatomical and physiological characteristics. Plants were collected from populations of high density (over 50% of colonization capacity) and low density (less than 50% of colonization capacity) and cultivated under controlled greenhouse conditions. Plants from both populations were grown in plastic trays containing 4 L of nutritive solution for 60 days. At the end of this period, the relative growth rate, leaf area ratio, net assimilatory rate, root/shoot ratio, leaf anatomy, root anatomy, and catalase and ascorbate peroxidase activities were evaluated. Plants from high density populations showed increased growth rate and root/shoot ratio. Low density populations showed higher values of stomatal index and density in leaves, as well as increased palisade parenchyma thickness. Root epidermis and exodermis thickness as well as the aerenchyma proportion of high density populations were reduced, these plants also showed increased vascular cylinder proportion. Only catalase activity was modified between the high and low density populations, showing increased values in low density populations. Therefore, different Typha angustifolia plants show differences in its anatomy and physiology related to its origins on high and low density conditions. High density population plants shows increased growth capacity related to lower apoplastic barriers in root and this may be related to increased nutrient uptake capacity.

Knowledge of tooth anatomy is of great importance in the practice of dentistry, especially in oral rehabilitation. For the teeth to fulfill their functions, it is necessary that their anatomic shape is correct. This research aimed to evaluate the theoretical and practical knowledge of dental anatomy acquired by students of pre-clinical course regarding quality of anatomical restorations performed by these students before and after a didactic-theoretical reinforcement. For the evaluation of theoretical knowledge, a questionnaire with closed questions about dental anatomy was used. To evaluate the effect of didactic reinforcement on dental sculptures, two groups of 15 students from Pre-clinical were assessed. One group received tutoring on dental anatomy and the other did not. The assessment and comparison between the groups were made using a pre-determined score. The restorations were carried out in wax on artificial teeth from P-Occlusal. With the experimental results of the study, the comparison between the scores obtained on the sculptures for the two groups was performed using ANOVA. The Fisher exact test was used to compare the frequencies of correct answers in the questionnaires. For all analyzes was considered an ?? = 0.05. Stata 11 program was used for the analysis of the data. The theoretical evaluation revealed no significant difference (mean ?? SD) between G1 (8.51 ?? 0.66) and G2 (8.62 ?? 0.91) in the notes previously obtained for this study (p = 0.725). In evaluating dental sculpture...

An interventional cohort comparison study with pretesting and post-testing in semesters 1 and 2 was undertaken of 159 medical students in year 3 of the MMBS course at the University of Adelaide in 2010. The intervention comprised the provision of a number of additional online resources in semester 2. Students' views on online anatomy were also sought by a questionnaire delivered at the end of semesters 1 and 2 and via a small focus group at the end of the study. Anatomy assessment results after the introduction of online anatomy were compared with a total of three control semesters in 2009 and 2010. There was >90% broad agreement before the intervention that wet specimens, tutors and discussions with other students helped students learn anatomy. After the intervention, these views remained, but there was additionally >90% broad agreement that text books helped them learn anatomy, that they had good access to anatomical specimens, and there was less agreement that lectures helped. The intervention left students' views on online anatomy largely unchanged and made no significant difference to summative assessment scores. Focus group discussions revealed that students want anatomy tutors to help direct them to reputable and relevant sites. The provision of more online resources in anatomy did not affect student views or learning outcomes. While students may need help from tutors in selecting appropriate online resources...

Es posible generar la malla de la piel a partir de la anatomía interna. Este artículo presenta un método que recibe huesos, un conjunto de músculos y un conjunto de órganos complementarios para generar la piel. El método inicia en el fondo de la anatomía y genera una serie de puntos clave que luego proyecta en un plano espejo que corta la criatura por la mitad. Una vez en el plano, los puntos son triangulados y reflejados. Posteriormente, la malla de la piel es ajustada expandiéndola y contrayéndola hasta que está a una distancia predeterminada de la anatomía. Finalmente, el pelo es generado con desplazamientos a partir de malla de la piel. El método depende del conocimiento anatómico para generar los puntos clave, pero elimina la necesidad de una malla de piel preexistente. La malla creada es anatómicamente consistente con la anatomía de la criatura.

Background: Medical knowledge and students’ demands are under continuous changes and learning process must adapt accordingly. We retrospectively analyzed students’ evaluation of three different approaches employed in our course of Clinical Anatomy in the last decade. Methods: The University of São Paulo Medical School has a systematic evaluation of each discipline where students grade 38 different topics ranging to physical conditions to the quality of the classes. In this study, different methods to teach Clinical Anatomy to 2nd and 3rd year students of Medicine were confronted to the students’ evaluations, comparing the general appreciation of the course in different teaching approaches. We analyzed the changes in the Anatomy course from 1994 to the present and their impact based on the students´ evaluations. Results: Significant improvement in general evaluation was observed when the course changed from Problem Based Learning technique to a more formal approach with theoretical classes given by specialists, most of them invited from other Clinical Departments of the University. A still better evaluation was obtained as the practical demonstrations focused aspects showed in theoretical classes, which were given mostly by specialists trained in Anatomy. Discussion: Students' evaluation allows course coordinators to redirect objectives and teaching methods to adjust the course format as needed. Performance in final exams may also be analyzed together so effectiveness of the teaching method can be measured along with students’ satisfaction. Conclusion: Continuous feedback from students is essential to course coordinators to adequate strategies to face the modern challenges in the teaching/learning process and obtain the best results in courses of Clinical Anatomy.; Introdução: O conhecimento médico e a demanda docente estão em constante e progressiva mudança e os processos pedagógicos devem ser adaptados conforme as necessidades para prover o máximo rendimento.
