Quantitative and morphological analyses of different types of human liver

Morphological variations in the human liver have been classified as congenital or acquired, although some mayresult from pseudo-injuries incurred during medical investigation. The present study comprises a systematicanalysis of the anatomical variations exhibited by 61 formalinised and glycerinated adult human livers derived from a collection maintained at the Institute of Anatomy, Universidade Severino Sombra, Vassouras, RJ, Brazil. The vast majority of the organs analysed could be classified according to the seven morphologicalliver types previously established, although two additional liver types were identified and described. Detailedknowledge of anatomical variations in the human liver could be valuable in improving diagnostic proceduresand in attaining a better understanding of pathological conditions associated with some liver diseases.

Practice of dissection as teaching methodologyin anatomy for nursing education

This study is focused at nursing education in the biological and health sciences field, specifically in terms ofknowledge of anatomy and the application of dissection as a teaching practice in the light of active pedagogies.The objective was to assess the importance of the practice of dissection to teach anatomy in a graduationcourse in nursing. The hypothesis that the students would be more interested in discipline if the teachingmethodology used was based on creative and constructivist methods, in relation to traditional teachingmethods. The sample comprised 37 students, among those who actually had the practice of dissection andthose who had not in a federal university. The mediation of the teacher and the contact with classmates duringthe discussions in the course of “learning to learn”, are important factors in the training of the academic inthe view of the active methodology. The performance of the student as active subject in the teaching processallowed the construction of a concrete knowledge. The constructivist methodology associated with dissectionenabled the construction of know-how and greater interactivity between students and teachers involved in theteaching-learning process.
