| The tissue pieces of palatine tonsil were collected from different postnatal age groups of sheep from the Corporation Slaughter House, Perambur, Chennai. The palatine tonsil consisted of a surface epithelium, capsule, tonsillar lobes, crypts, crypt epithelium and tonsillar follicles. The surface epithelium over the palatine tonsil was made up of non-keratinized stratified squamous epithelium in all the postnatal age groups studied. The palatine tonsil was clearly demarcated from the surrounding structures by a distinct connective tissue capsule and one septa dividing the tonsil into two lobes. The surface epithelium was invaginated into the substance of the tonsil to form primary and secondary crypts in each lobe. The crypt epithelium covered the regions... |

| Obesity is a prevalent disease in Chile. The multitude of cause factors makes it a complex disease and therefore very difficult to treat, since its roots lie in the earliest stages of life. We evaluated pupils from 21 municipalized primary schools, in rural and urban communities from the 10 districts of the IX Region. The sample consisted of 275 subjects in Kindergarten and first year primary school in the year 2008, who were monitored over two years. The results show a trend indicating an increase in the prevalence of obesity in the sample, the difference being statistically significant, p=0.000. These results show that obesity is increasing, and that more action is needed to slow this disease occurring from early childhood. |

| Formaldehyde is a chemical, which is used traditionally for fixing the cadaver. It is vaporized during dissection and practical studying on cadaver. Studies show that this vapor can cause some clinical symptoms such as throat, eye, skin and nasal irritation. This study was designed to determine the histopathologic changes of rat tracheal mucosa while all of the experiments were exposed to formaldehyde for 18 weeks. This study was performed on 28, 6-7 weeks postnatal albino Wistar rats. The rats were divided into 3 case groups (E1: 4h/d, 4d/w; E2: 2h/d, 4d/w; E3: 2h/d, 2d/w) and 1 control group. The tracheal specimens were sectioned and stained with H&E technique for histopathologic study. An epithelial disorganization, cilia disappearance, slight... |

| The present study assessed central nervous system (CNS) and immune system changes in murine fetuses after cyclophosphamide (CP) exposure during intrauterine life. A single CP dose of 0, 10, or 20mg/kg body weight was administered by intraperitoneal inj ection to pregnant mice (20/group) on day 11 of gestation (GD 11) and fetuses were evaluated on day 19 of gestation (GD 19). Fetuses were examined for external changes, and then the brains and thymuses were removed for further evaluations of histological changes, protein content, apoptotic cell count, DNA fragmentation, and in vitro cell proliferation using 1 fetus/litter for each assessment. Brains and thymuses from CP-exposed fetuses were smaller in size and distorted in overall shape compared to those... |

| The radial nerve is a terminal branch of the brachial plexus that innervates the entire posterior compartment of the upper limb. Researches have shown that the branches can contribute to innervation of the muscles from the anterior compartment of the arm. This study sought to identify branches of radial nerve for brachialis and coracobrachialis muscles and its clinical value during surgery. Dissection was performed in 60 arms, from 30 corpses selected from the Human Anatomy Laboratories of Universidade Estadual de Ciências da Saúde de Alagoas (UNCISAL). In each arm, three segments of the same proportion were considered (proximal, middle and distal) in order to observe the number of radial nerve branches to brachialis and coracobrachialis muscles. Branches... |

| Since the beginning of the century in various countries, investigations to determine the anthropometric characteristics of a population were carried out. The issue of miscegenation in Brazil is of great importance in this study to define a population representative data on the cranial anthropometry. The large size of Brazil, with 8.514.876 km2 leads to an investigation between the two extreme regions of the country: North and South, because of the ethnic composition of their colonizers. This study aims to investigate, compare and rank possible differences in cephalic index of the populations from these regions of Brazil. Therefore, an anthropometric study was performed at the School of Aeronautics Expert (single training center for graduates of Brazilian... |

| Exhibitions of plastinated specimens are popular around the world, but most people are not aware of the basics of plastination process because they are not interested in reading the related writings. Comics are an attractive medium and could solve this problem. The objective of this study was to enhance public comprehension of plastination using comics. Three topics were selected for the comics: the traditional ways to preserve dissected cadaver specimens, the plastination technique used to resolve the problems of the traditional ways, and the public display of the plastinated specimens. The 67 comic frames were drawn in simple style. The comics were available online (anatomy.co.kr) free of charge. The original files of the comics will be provided to those... |

| El cefalograma lateral es una radiografía que se usa rutinariamente en la ortodoncia. Este tipo de radiografía plana es la mejor opción para investigar las características morfométricas de la silla turca, determinando su tamaño y forma y sus eventuales variaciones. Taveras & Wood han descrito un método, para determinar el tamaño de la silla turca en radiografías. Midiendo el mayor diámetro anteroposterior de la silla turca y la profundidad de ella desde el punto más bajo a una línea que conecta la cima del dorso de la silla al tubérculo selar. Esto nos motivó llevar a cabo un estudio de estas características, para lo cual se registraron las correspondientes observaciones en 88 teleradiografias laterales, de las cuales correspondían a 44 individuos... |

| The present ultrastructural observations demonstrate the presence of six cell types in the pars distalis of non-pregnant and pregnant bats of Taphozous longimanus. In the pars distalis of T. longimanus, STH cells are round to oval with eccentrically placed nucleus, numerous secretory granules and well developed Golgi indicate a cell under vigorous synthetic activity while those filled with secretory granules with reduced Golgi complex suggest reserve or storage state of cells. LTH cell is characterized by the large secretory granules, dilated endoplasmic reticulum and numerous mitochondria in the cytoplasm which indicate that these cells are hypertrophied and synthetically very active during pregnancy. ACTH cells are found either singly or in groups and... |

| During routine dissection, an unusual formation of median nerve was detected in the right upper limb of a 55 year old male cadaver. The median nerve had an additional contribution from lateral cord. The two branches of the lateral cord designated as upper and the lower branches were observed at different levels. The upper branch was in close contact with the third part of the axillary artery and it crossed the vessel anteriorly to unite with a branch of the medial cord to form the median nerve. The median nerve thus formed was related medially to the axillary artery (instead of the normal position of being anterolateral). The median nerve descended below and was joined by an additional lower branch from the lateral cord. Interestingly, the ulnar nerve... |

| Knowledge on internal dental morphology is extremely important to the correct execution of the treatment and modeling of root canals. The aim of the present study was to analyze, "in vitro", the configuration of the canal system in the mesial root of 180 maxillary first molars obtained from a Brazilian sample. The teeth diaphanized in order to confirm the presence of the MB2 canal and to determine the internal anatomy. Only in 41 % of the teeth the orifice of MB2 canal emerged from the pulp chamber floor. Among teeth two apical foramina were found in 23.3 %, a single apical foramen was observed in 15,5 % and three apical foramina were present in 2,2 %. Considering the hole sample, the MB2 canal was observed in 65.4 %, merged with the MB1 or branching from... |
