| Knowledge about human skull asymmetry in normal dry specimens is useful as a parameter for medical and dentistry practice. Skull base was investigated with the objective to validate the method of indirect measurement with digital pictures and to evaluate the degree of asymmetry from human skull base in different ages. We analyzed 176 normal identified human skulls, divided by age in the following groups: Fetuses, newborn, children and adults. Measures were taken from a central point: pharyngeal tubercle and 4 lateral points: foramen ovale, foramen spinosum, carotid canal and stylomastoid foramen using digital biometry after a comparative validation with directed method performed with caliper. Results were presented as asymmetry indexes and data were... |

| The anatomy of mammal's lung air space constitutes the bronchial tree which disposition is associated to air flux dynamics. Casts obtained from human, pig and rat lungs were studied to analyze possible differences of the bronchial tree architecture in mammals with diverse dimensions and posture. Air spaces were filled with polymers through trachea followed by acid corrosion. Tracheal and main bronchial division's diameters were measured to relate with body mass using allometry. The results revealed a dichotomic bronchial branching pattern in the human casts and a monopodial pattern in animals. In allometric relationship trachea was larger in rats, then pigs and lastly in humans, differences were statistically significant, the same occurs in right bronchus,... |

| Chordae tendineae architecture and their junction with papillary muscle were studied with scanning electron microscopy, comparing human and swine hearts. Papillary muscles with the corresponding chordae tendineae were obtained from human and pig (Sus scrofa) hearts after exposition of the left ventricle cavity, fixed with 4% formaldehyde. The specimens were sectioned in small samples and divided in four groups, a control one and the others submitted to digestion in a solution of 2.5% sodium hypochlorite in saline solution during 5, 10 and 15 minutes respectively. The specimens were washed and fixed in 1% osmium tetroxide in cacodylate buffer, kept in 1% tannic acid for 30 minutes, dehydrated and critical point dried, mounted and sputtered with gold. The... |

| Del cráneo humano se obtienen datos métricos para el diagnóstico de sexo, edad y afinidad racial. El propósito de este estudio fue determinar, por medio de dimensiones lineales faciales y craneales, una función discriminante e identificar aquellas dimensiones más útiles, para predecir el color de piel a partir de cráneos. Se analizaron 208 cráneos de la colección de la Universidade Federal de São Paulo, pertenecientes a individuos con afinidad racial para blanco, negro y mulato, de acuerdo al registro. Se determinaron las siguientes dimensiones: Biéurica, Glabela-Opistocráneo, Basion- Bregma, Nasion- Prostion, Bicigomática, ancho máximo de la apertura piriforme y la distancia Nasion-Espinal. Se realizó un análisis estadístico con ANOVA de un factor, test... |

| This article analyzes the performance of diagnostic tests for sex determination by examining human skulls, using the Baudoin condylar index. For this study, 215 skulls were examined, and the maximum dimensions (length and width) of the right and left occipital condyles, were noted. With these data, we calculated the Baudoin condylar index and determined the level of agreement between the values for the left and the right side, the sensitivity of the method, the accuracy of the tests and the positive predictive value for each sex. The level of agreement in the diagnosis based on both sides was 65.58% (of which 83.09% were of women, and 63.88% were of men). The overall accuracy was 41.39%, and a greater sensitivity was seen in women (52.1% right side and... |

| This study assesses the quality, as a diagnostic test, of the main indicators of morphological sexual dimorphism through direct anthropometry, biostatistics tools and clinical epidemiology. This study used 284 skulls of adult Brazilians, of which 187 were male and 97 female. A study of the cross-evaluation of the diagnostic test was performed; it was a qualitative approach based on visual examination of 16 traditional indicators of morphological sexual dimorphism, where each indicator determined the level of accuracy, sensitivity, predictive values, likelihood ratios, and odds ratio. All indicators studied had high levels of accuracy (84.7572.89%). The best indicators were found in traits whose formation is related to the insertion and action of major... |

| The sex determination from human skulls can be made by means of morphologic and morphometric methods have been broadly studied. These methods contribute with objective data; however, they present interpopulational variability. The purpose of this article is to determine sexual dimorphism using lineal dimensions in a sample of human skulls collection belonging to the Universidade Federal de Sao Paulo (UNIFESP), calculating the discriminant function. To complete the selection approaches, 226 skulls were analyzed. Mensurements were carried out among the following reference points of the skull: right Eurion- left Eurion (Eu - Eu), Glabella-Opisthocranion (Gla - Op), Basion - Bregma (Ba-Br), Nasion - Prosthion (Na-Pr), Bizigomatic (Zi-Zi), Maximal width of the... |
